Necessary premise. I am not a lawyer, and what follows is not legal advice. It is a description of a mechanism that I see ignored every day by adults, often convinced they are safe.
The belief is this: I wrote something heavy, then I changed my mind and deleted it, so nothing happened.
It doesn't work that way, and it's worth understanding why.
Deleting removes visibility, not the fact
When you delete a comment, you are removing only one thing: its public visibility from that moment forward. You are not touching anything else.
You are not touching the screenshot that someone took in the minutes it was online, and in heated discussions screenshots are always taken, often by the person who felt attacked. You are not touching the notification that has already arrived on the phone of someone who replied to you, which in most cases contains the full text. You are not touching the data that the platform stores on its systems, which remain obtainable at the request of the judicial authority even after some time.

Your action has a strong effect on you, because you no longer see that comment. It has none on the position of whoever read it.
What Italian law says, in two lines
Defamation in Italy is a crime, provided for by Article 595 of the Penal Code. It occurs when, by communicating with more than one person, one offends the reputation of someone who is not present.
Two details matter more than everything else.
The first. The Code provides for an aggravating factor when the act is committed through the press or any other means of publicity, and case law now consistently applies this aggravating factor to social networks, precisely because of the audience they reach.

The second, the one that most disorients. Communicating with more than one person does not mean being in public. A closed group with other people meets the requirement. The condominium chat, the neighborhood group, the work group. The idea that inside a private group you can say anything is one of the most widespread and least founded beliefs of Italian digital life.
Alongside criminal law, there is the civil route of damage compensation, which has its own logic and timing and which in practice is the one that most often truly weighs on the wallet.
Anonymity is more subtle than it seems
The profile with a fictional name gives a feeling of distance that the facts do not confirm.
At the moment a proceeding is opened, platforms respond to the requests of the judicial authority, and the technical data associated with an account allows in many cases to trace back to who uses it. It is not immediate, it is not automatic, and it does not happen for any comment. But it happens, and when it happens, your fictional name becomes your name.

It is worth adding another, little-known point. Even sharing defamatory content written by others can expose the person who shares it. The I only shared it is not the protection that many imagine.
It is not an invitation to report everyone
Let's make it clear, because the risk of reading this piece backwards is high.
I am not suggesting reacting to every offense with a lawsuit. It would be tiring, expensive, and in the vast majority of cases useless. The time required is enormous, and should only be spent when the damage is real and documentable.
I am saying something else, much simpler and useful to both parties.
To the writer. The comment written in ten seconds of anger has a longer life than the anger that produced it. That asymmetry is the whole problem.

To the receiver. You are not without tools as it seems while you read it. The screenshot with date, URL, and visible profile is a concrete thing, and keeping it costs nothing. If one day it will be useful, you'll have it. If it won't, you will have stopped feeling at someone's mercy.
The operational conclusion is one, and it applies to anyone with a phone in hand. Always write thinking that that text will remain readable even when you have already changed your mind.
Because that's exactly what happens.
