The bans come from reports, people are more aggresive reporting others and GMs investigate alot faster. If you dont bot 24/7 and watch your bots you will never get banned. If you bot 24/7 they will ban you without checking anything ( so monitoring wont help ), if you bot like a human with breaks and shit, they are forced to make sure you bot, so they teleport you around first and stuff, if you watch it, you wont get hit. Ive expierenced this like 3-4 times already.
