I got the same ban, made an appeal on EB site, that got same answer as everybody else, wanted to make an appeal on pbb site, but it says that it's not in MBI, so how does that work??
next thing:
on gcc site the time stamp says 21:04, my guild in swtor raids at that time so i wasn't even playing bf4 when i got that ban, huh ??
finally i got in touch with ea support, and a guy there said that he doesn't see my account being banned, again huh??
and he said that they already had few other ppl complaining about it... and to help me out i got a discount coupon to buy another copy but since i don't know what triggered the ban i'll stay way clear of any PB protected game.
Regards
Bart
