I want to buy the hearthbuddy I see that does not have many bans. those are banned for abuse or is there some detection?
its kinda random. if u get reported (ticket to blizzard) by a player u faced thinking u used a bot and blizzard does check it u could end banned. no real system.
I have 2 accounts, 1 main - which I botted alitte with, and 1 i botted alot with.. I've been banned on my main whom i botted a little with :\ bad luck here aswell.. but there has been quite some time since last ban-report.. I think they are saving up for a big banhammer.. but it may be just speculations.
From what research I've done on this site and Google, Blizzard doesn't have a bot detection system. I'm 90% sure that bans happen by first being reported by another player. Once a player reports you, it's only then that Blizzard investigates your account.
