Ad blocking is a cat and mouse game. Anti censorship is a cat and mouse game. Anti fraud is a cat and mouse game. Anti spam is a cat and mouse game. I don’t see people giving up so easily on those problems.
I can't think of any way to solve this problem if a majority of clients in a swarm is malicious.
The maintainers reject the proposal to block by client ID. But they never consider the second method.
