There are two routes.
On the forum: use the Report button under the post. Reports are read by Warden, the staff member who handles trust and safety. The Community Rules ask you to report rather than reply to or call out the person in the thread, because that usually makes the thread worse and does not get it handled faster.
On the helpdesk: open a ticket in "Report a scam, abuse or user". Include:
- The exact link to the post or profile, or the Discord or Telegram username and where you saw it.
- What happened, in a few plain sentences, and when.
- Anything that shows it, copied as text or in a screenshot with private details blurred.
- Never your password, tokens or keys.
Reports about sexual content involving minors, doxxing, or credible threats are the most serious. Those are permanent bans and the first is also reported to the authorities.
For what happens next, see "What happens after I report something?".
