Best ideas I got are random captchas, make lemmy invite only, and/or set up some sort of verification system.
Maybe the captcha failure rates visible on a user profile. These tactics can scare off new users but letting lemmy get taken over could be worse than doing nothing.
I watched twitter slowly get flooded with bots. I don’t want the same to happen here.
