That seems silly. At the end of the day, going a long time without banning them is just letting them bot without consequences for months at a time. Literal unfettered access to bot-farming for months as opposed to…some of them having access to a different botting program that might take…months…to identify…?
I’m not a cyber security guy, but if an average player walking around in the world can spot a bot with ridiculous ease, I feel like it shouldn’t be that hard for Blizzard to notice.
