i find this to be quite miracelous as i have been restricted 5 times and lost bnet connect about 3 times from the ladder on. these occasions also occured only when i was madmuling as fck. with 2computers (joining the same game with 6 characters within a minute) so i kind of desrved it i guess.
thse bans also did not last for more than 5 mins
i usually baalrun with 2 characters simultaniously, i join like 40-50 games each hour while using the same adress.
i don't get bans from that either. no problems here...
and the only time i got rollbacked was when i sold a pally shield with 23 resi, got rollbacked and saw a game with n 3soc pally shield, sold it for ist and when i made a hoto 32, later 37. liking rollbacks by the minute
