Who talks here, and what remains

The chat rules

Messages appear immediately and anyone who opens the page sees them, in every language. Whoever writes is responsible for what they write. Not allowed:

• insults, threats, harassment towards other readers or anyone else;
• hatred or discrimination based on origin, religion, gender, orientation, disability;
• other people's personal data (addresses, phone numbers, emails, documents);
• spam, advertising, chain messages;
• illegal content of any kind.

A message can be at most 500 characters long and contain two links, which stay as text to copy. You can write one message every few seconds and a limited number per day. After thirty days every message is deleted entirely.

Anyone who breaks the rules may have their messages removed and lose the ability to write. The chat is not watched at every moment: that is what reports are for.

Reporting a message

Next to each message there is a small flag ⚑. You choose the reason, can add details and, if you want to know what gets decided, your email. The report reaches moderation immediately. When two different people report the same message, it is suspended until a decision is made.

The decision (removing the message, blocking whoever wrote it, or leaving it) is taken as soon as possible and sent by email to those who left their address; it can be contested by replying to that email. For serious or urgent content, or for requests from the authorities, write to the contact below.

What data goes through the server

• IP address. The service behind the chat, the message board and the reactions does not store the IP address: it computes a fingerprint of it, encrypted with a secret key, used only to limit submissions, to count a vote only once and to block those who break the rules. The address cannot be recovered from the fingerprint. The web server keeps no access logs.
• Chat. Text, chosen name (optional), time and fingerprint: deleted after thirty days. Next to the name appear four characters derived from the fingerprint, to tell apart people writing without a name. The chat only appears when at least two people are on the page: to count them, every open page sends a random code every twenty seconds, which the server keeps only in memory for less than a minute and never stores.
• Reports. Reason, details, email (optional) and fingerprint: kept for six months, to be able to reply and to document decisions.
• Message board and reactions. Messages and name (optional) remain as long as the page exists; the fingerprint of messages is deleted after thirty days, that of votes remains as long as the vote does, because it is the only thing that prevents voting twice.
• In your browser. No cookies from the site. The browser's local storage keeps the theme, the language, the name used in the chat and the last message read: they never leave your device.
• External services. Visit statistics come from Umami Cloud, without cookies and only as aggregate counts. Typefaces come from Google Fonts, which receives the visitor's IP address in order to send them.

Legal basis: the legitimate interest in running the chat and the message board and keeping them free from abuse (art. 6.1.f GDPR); for the email in reports, the choice of whoever leaves it. You can ask to see or delete your data by writing to the contact below; you can always lodge a complaint with the Italian data protection authority, the Garante per la protezione dei dati personali.
