Actually, when i got banned, i though it was kind of a bug. i keep playing on other deathmatch servers to warm me up before doing matches.
However i only recently notice that when i tried to join any ambrosia server, then pushing the console key, i could see that i was actually banned
And since i didn't know what to do to unban me, i did nothing.
One day, i was playing with drama, i told him i was banned from these servers, without knowing he could do something for me, then he told me to do an unban request on your forums.
So that's what i do now, thanks for the comprehension.
