As you can see, there is a massive spam wave going on on Lemmey based instances.
This can be avoided by enabling CAPTCHA with signup and also LIMIT the registers per X seconds!
Currently the accounts are idle but this can change soon.. Please take action NOW!
Ofc there are bot nets that can defeat it but it should always be an option since the "cheaper ones" cannot and beat in term some spam
The rate limit for signup is a way better option and should also be explored
I'm curious to see how Hashcash it would handle though
