Defamation on Facebook and Social Media in Italy

A Facebook post, a public comment, or a message in a group chat is where most real diffamazione disputes happen today, and it raises questions the base offence does not fully answer on its own. This page covers what is distinctly social about diffamazione: why the platform matters, when sharing or liking crosses a line, how to preserve evidence that holds up, what to do about an anonymous poster, and a graver offence this is sometimes confused with.

For the underlying offence itself and how diffamazione differs from ingiuria, see defamation in Italy: a criminal offence. For the querela procedure and deadline, see filing a defamation querela. This page assumes that background.

The same offence, with one aggravante doing the real work

Diffamazione on social media is prosecuted under the identical art. 595 c.p. that applies to any other case: offending someone's reputation, while they are not present, by communicating with at least two other people. What social media adds is not a new offence, it is the third comma aggravante, made where the offence is committed «col mezzo della stampa o con qualsiasi altro mezzo di pubblicità», through the press or any other means of publicity.

That phrase predates social media, but Cassazione applies it to ordinary posts on a settled basis, including in a 2021 ruling addressing Facebook specifically. The reasoning is about reach, not the platform's name: a post visible to an indeterminate or appreciable number of people fits «qualsiasi altro mezzo di pubblicità» regardless of what the mezzo actually is. Where it applies, the penalty rises to reclusione from six months to three years or a fine of at least 516 euro, in place of the base offence's ceiling of one year or a 1.032 euro fine.

A concrete case: someone posts on their public Facebook profile a false claim that a local shopkeeper waters down products sold to customers. Because the profile is public and searchable, the post can reach an indeterminate audience, which is what the aggravante targets, independently of how many people actually saw it before it was taken down.

Does the target have to be named?

No. Identifiability is enough, which is where many real disputes sit. A parent posts in a school's parents Facebook group, without naming anyone, that «the teacher who is always late on Tuesdays is clearly not taking this job seriously». If other parents can work out exactly which teacher is meant, that identifiability satisfies the requirement even without a name.

The same logic cuts the other way for a defence. A genuinely vague complaint describing several people, or a whole category rather than an individual, does not identify anyone in particular and does not support a case against a specific person.

Reach decides the aggravante, not the app

Not every message sent through a phone is a mezzo di pubblicità. A message inside a small, closed group of four or five close friends or family members lacks the capacity to reach an indeterminate audience, so the aggravante is not automatically in play there, even though the conduct can still be base diffamazione if it reaches at least two people while the subject is absent.

Contrast that with a public or open channel. A public Telegram channel with two hundred subscribers, or a Facebook group anyone can join, behaves much more like the press analogy the aggravante was built for: an appreciable, effectively indeterminate audience, whether or not every subscriber actually reads it. The deciding fact is the message's actual reach, not the app carrying it.

Authoring, sharing and liking: not automatically the same act

Art. 595 c.p. requires communicating an offensive statement about an absent person to at least two other people, and that definition does not care who wrote the words first. Someone who shares another user's post to their own followers is, independently, communicating that content to a further audience, so a share can expose the person who shared it, separately from whoever wrote it originally.

A like sits differently. It adds no words of its own and does not restate or amplify the claim the way a share or a comment does, which makes it comparatively weaker ground for a case. That is a difference of evidentiary weight, not a blanket exemption, and a like paired with an endorsing comment is assessed on the comment's own content.

Evidence: screenshots, and why a bare one is weak

Preserving what was posted, and identifying who posted it, are usually the real bottleneck in a social media case, more than the underlying law. Our page on filing a defamation querela covers the general evidence problem; here is what is specific to a screenshot.

Art. 2712 c.c. gives a digital reproduction, including a screenshot, piena prova, full evidentiary weight, of what it shows, but only «se colui contro il quale è prodotta non ne disconosce la conformità ai fatti», if the person it is used against does not dispute that it matches reality. A cropped image with no visible date, URL or account name is comparatively easy to dispute on that ground. A capture that shows the full post, the poster's profile, the platform's own URL bar, and a visible date and time is considerably harder to disavow, and acting before the post can be edited or deleted matters.

Where more is at stake, stronger preservation exists: a screen recording that shows the URL bar while scrolling, sending a copy to yourself by PEC to fix a timestamp, or asking a professional to certify the capture, all sit above a bare phone photo on the evidentiary ladder.

Identifying an anonymous poster

Where the account behind a post is anonymous or pseudonymous, a private individual generally has no direct way to make a platform reveal who runs it. That limitation is one of the practical reasons the querela mechanism exists: once a complaint is filed and a pubblico ministero opens an investigation, formal requests to a platform, and specialised units such as the Polizia Postale, the Polizia di Stato's cybercrime division, become available as investigative tools a private citizen acting alone does not have.

Reporting to the platform is a separate, parallel track

Reporting a post to Facebook, Instagram or another platform under its own community standards can lead to the content being taken down, but it runs on a different track from the criminal querela process. A platform's internal review is not bound by the three month querela deadline and is not a legal finding that diffamazione occurred, just as a platform declining to remove something does not mean no offence took place.

Someone who wants both outcomes, the content down and the underlying conduct addressed, generally needs to pursue both tracks, since neither substitutes for the other.

Not diffamazione: art. 612-ter and non consensual intimate images

Sharing sexually explicit images or video of someone without their consent is not diffamazione, even where it happens on social media, and treating it as an ordinary defamation matter steers a reader toward the wrong remedy. It is a separate, graver offence, art. 612-ter c.p., diffusione illecita di immagini o video sessualmente espliciti: reclusione from one to six years plus a fine from 5.000 to 15.000 euro, rising further where committed by a current or former spouse or partner, or through IT or telematic means. Legge 2 dicembre 2025, n. 181 added a further aggravante, raising the penalty by a third to two thirds, where the conduct amounts to gender based hate or discrimination against the victim.

The querela term for this offence is six months, not the three months for diffamazione, and the remissione can only be made processuale, within the proceeding itself. The case proceeds d'ufficio, without needing a querela, in the aggravated circumstances the article sets out or where it connects to another d'ufficio offence. Someone in this situation should pursue this specific route, not an ordinary diffamazione complaint.

Frequently Asked Questions

Is posting something false about someone on Facebook a crime in Italy?

Yes, on the same terms as any other diffamazione. Art. 595 c.p. punishes offending someone's reputation while they are not present by communicating with at least two other people, and Italian courts treat an ordinary social media post as falling within the third comma aggravante, reclusione from six months to three years or a fine of at least 516 euro, because it can reach an indeterminate audience.

Does the post have to name me directly for it to count?

No. Cassazione applies the aggravante wherever the description lets other people work out who is meant, even without a name. A post that describes someone in enough identifying detail can still trigger it.

Can I get in trouble just for sharing someone else's defamatory post?

Potentially, yes. Sharing a post to your own followers communicates its content to other people independently of who first wrote it, which is exactly the element art. 595 c.p. requires. Whether the aggravante for reach applies on top of that depends on how many people your own share could reach.

What about just liking a defamatory post?

A bare like adds no new words and is a comparatively weaker basis for a diffamazione case than authoring or sharing the content, since it does not itself communicate a new statement. That does not make it automatically risk free, and it is assessed on the same facts as any other conduct: whether the target was absent, whether it reached other people, and whether reputation was actually harmed.

Is a screenshot enough to prove what was posted?

It is the starting point, but a bare screenshot is comparatively weak, since art. 2712 c.c. only gives it full evidentiary weight if the other side does not disavow that it matches the facts. Capturing the full post with the profile, a visible URL and a timestamp, before the content can be deleted, strengthens the record considerably.

What if I do not know who is behind the account that posted about me?

This is common with anonymous accounts and is usually the harder practical problem, not a legal one. A private individual cannot compel a platform to identify a user; filing a querela opens the matter to investigation, where a formal request to the platform and units such as the Polizia Postale become available.

Does reporting a post to Facebook replace filing a querela?

No. Reporting content under a platform's own community standards is a separate, parallel track aimed at getting it removed. It does not carry the querela's three month deadline, and a platform's decision to remove or keep content is not a legal finding about whether diffamazione occurred.

Is sharing someone's intimate photos without consent the same as diffamazione?

No, and it should not be treated as one. Sharing sexually explicit images or video of someone without their consent is a separate, graver offence, art. 612-ter c.p., diffusione illecita di immagini o video sessualmente espliciti, carrying reclusione from one to six years plus a fine from 5.000 to 15.000 euro, with its own aggravating circumstances and a six month querela term. Someone in that situation needs that specific route, not the ordinary diffamazione procedure.
