why have I been banned?

I was playing one day last week and my friend danderman69 got banned for killing in the boxing ring which was right but then I asked why he was banned and for how long. I played for a bit and then left the server to play a different game but the next day when I tried to join I was banned.

I wish to know why but I think I know. If I'm right then it was because I accidently killed someone in the boxing ring. I said in the chat sorry I didn't mean tom and none of the admins on at the time told me off so I wasn't warned or kicked before the ban was placed.

I only wish to know why I was banned and for how long.

Thanks Robot Soldier.

You were breaking rules, idk what happened there or what were you doing and it was kinda long time ago, i'll let the admin that banned you decide if he wants to keep it permanent or lift the ban

k. first of all. it is a long time ago. next i have banned a lot of ppl since then and it is much to remember. but i seems that evryone that come here and protest a ban has accidently done something. since we can say either way we have to belive in what we see and ban ppl because of that. since we didnt heare from you before now i dont see that you care too much about the server. so i think we let the ban stay

ok but all i want to know now is exactly why I was banned. If you tell me then you won't hear from me again

its in my previous post, you were breaking rules,
i wasn't there so idk ,cpt.eagle stated that he don't remember and since it was long time ago i can't blame him,it was before i have closed the server for F2P since they have been making most of the problems there, we have like 1000 bans in database ,thats why he won't be able to remember your ban, unless he wrote down note for himself on paper or here to remember.
i can only guess that you might have been shoot/melee killing ppl in the boxing arena or have been closing the door there, since that rule is forced ,so heavies can box and have fun doing so uninterrupted
