Based on experiences with other forum software I'm wondering what to do about bots. Other software has a bot list already incorporated. XF does not appear to have this. I believe bots should be treated differently than guests. Should specific desired bots have a bot usergroup with permissions? How do you disallow all other bots? What should be in robots.txt?
Registration will be handled by manual approval with Q&A Captcha and StopForumSpam. This should limit spambot registration.
