I agree if Blizzard wanted to expend quite a considerable amount of resources to catch people botting they could. And Blizzard's bank roll is quite a bit bigger than Bosslands. If they REALLY wanted to shut all of us down. They could. If your smart and dont call attention to yourself by making shitty HB paths, you wont get caught. If you get reported a bunch by real people saying your botting you'll get banned. Thats about it.
If blizzard had a "auto ban for lots of auctions and excessive login time" too... i would have been f****d when LK expansion came out.
