Same here. When I think about the bots it's mainly about possible future issues.
At the moment it would be a very inexpensive and simple way to attack nostr.
In fact I think that's a large part of why we are not ready for any serious adoption.

Maybe the #wot collaborative filtering could be more curating a blacklist instead of only white listing. New accounts would get a chance as long as as they are not muted by more than three trusted npubs.
I like this, but still have a concern that the number of bot accounts could far outpace real ones. Making it an overwhelming experience for users to filter accounts themselves.
