I was banned quite a time ago, so I may have forgotten the exact date.
Username(s) (order from most likely to least likely to be the username listed when banned) . (yes, that was one my usernames, most likely to be the one banned) DOCTOR SIMM Suicide Bomber
Approximate date was last year (2016) some time between September and December).
What I did wrong: I believe I killed an ally who was shooting me (most likely). The other possible reason was driving a jeep with explosives and blowing self up near an enemy tank and killing a nearby ally.
I have read the rules, and will abide by them.
EDIT: I'm not aware which server I was banned (I think after getting banned from the server I was in I was banned from all major servers).
