Send deletion event with vote system to relays. If X votes has been sent to a relay, the relay delete all events from the specified pubkey (scammer) + ban all futures events from this pubkey. Not perfect. It requires a specific action for each account. Or a centralized list of scammer pubkeys. Not ...

I wouldn't even know how to block them... 😔

PoW on replies

Client level opt out block lists.

Zap to reply, or a history of having zapped a user to reply? Perhaps the requirement for a linked wallet which could be checked for a sat balance before one can reply, and users could turn this on or off in their accounts. Just throwing some ideas around, maybe there is something in there.

Keywords / Hashtags filtering. Preferably client side.

Micro payment groups.

PoW, proof of burn, or payment for relay access and PoW to reply. Solving by heuristics at a relay level is difficult.

Mutes are just a list - why not tell clients to implement the ability to pull mutes fro additional lists that a user may pick, allowing a community approach to filtering on one side? On the other... I guess good implementations or methods to filter incomming posts; mainly thinking of strfry's Write...

Stats on what relays have the most and least of them could be useful to help pick relays.

Proof of work must be done.
