Damus currently has a report note button which broadcasts another event with a specific kind ID. Anyone could connect to relays and collect all the IDs of reported notes and do either good or bad things with this information. Other clients can add this button too, and can choose to not display previously reported notes (above a threshold etc).

In most jurisdictions you're supposed to report it to the police, so that they can identify who has accessed it and who attempts to access it next.

That's how technology works. If it works for you, it works for your most bitter opponent. If it limits your opponents, it also limits your dearest friends.

Choosing the right amount of freedom is always a balancing act.
