I feel like if you played by hand for 2 hours before botting for x amount of hours and then went back to hand all while not logging would look very suspicious.
I say that because human input is far different and less accurate/consistent than that of a bot.
Could be way off but that's just my opinion on it! I learned the hard way and got my old main since 2010 banned, but I was lucky enough to get it unbanned late last month!
