Reporting

draft optional author:jb55

A report is a kind 1984 note that is used to report other notes for spam, illegal and explicit content.

The content MAY contain additional information submitted by the entity reporting the content.

Tags

The report event MUST include a p tag referencing the pubkey of the user you are reporting.

If reporting a note, an e tag MUST also be included referencing the note id.

A report type string MUST be included as the 3rd entry to the e or p tag being reported, which consists of the following report types:

• nudity - depictions of nudity, porn, etc.
• profanity - profanity, hateful speech, etc.
• illegal - something which may be illegal in some jurisdiction
• spam - spam
• impersonation - someone pretending to be someone else

Some report tags only make sense for profile reports, such as impersonation

l and L tags MAY be also be used as defined in NIP-32 to support further qualification and querying.

Example events

  ...
}

Client behavior

Clients can use reports from friends to make moderation decisions if they choose to. For instance, if 3+ of your friends report a profile for nudity, clients can have an option to automatically blur photos from said account.

Relay behavior

It is not recommended that relays perform automatic moderation using reports, as they can be easily gamed. Admins could use reports from trusted moderators to takedown illegal or explicit content if the relay does not allow such things.
