Making user bots. Essentially, these look just like normal accounts, but are actually bots designed to spam, advertise in, and otherwise disrupt popular groups.
While tools like Join Lock have helped, they are not perfect because they make it way more difficult for actual people to join your group, just so that user bots can't - that sucks, big time. What you need is an easy (and fun?) way for humans to prove they're human, but easily filter out user bots.
Next week, I will announce a new @CalsiBot feature which does just that - if you want to test this out early, contact me
