3 accounts banned w/ active sub, Buddy no active sub not banned?

[Volleybalk]

So I just wanted to throw this out there, I had 2 10 year accounts banned with the wave, and a 1 week old account as well. I had botted Garrison stuff, Fishing, CR's and PvP. But I didn't do a lot of it frequently. I might have had it running 8 hours per day. A Friend of mine botted 24/7 PvP, Cr's Garrison, and Farming on 3 accounts and let his time expire about 2 weeks before the wave and none of his accounts were touched. I just don't understand :/ I guess it was just bad luck. lol
