We've implemented some changes to the bot detection algorithm. Hopefully it will keep most of the thot bots out of your groups in the future.
After receiving dozens of screenshots from many of you, we managed to find a new pattern that we deemed usable; although it is worth mentioning that this could cause some false positives.
If you see examples of real people getting kicked, please contact Nyxie or Rayg and let us know.
A special thanks to Z, Aurin and everyone else for diligently sending us dozens and dozens of screenshots of the bots joining your groups. This helped immensely.
