As Gasman and Renzy have said, there is somebody on j.ai who could be a ped0 luring other people searching for that kind of thing to their telegram. If you see this person, block them, report or delete their comment and try to get a ticket to report them on the official janitor ai discord. It seems very unlikely that they could be some sort of authority trying to make an arrest. If you see this certain user as detailed in Gasman's recent post, DO NOT ENGAGE WITH THEM, as it could be dangerous and problematic legally.

Thank you, and stay safe, everyone.
