I can tell you why you were banned, because I spoke to the admin at length a moment later.
Basically, Alphas Male said that
"No one messes with the MCG clan" and "he was kicked for his attitude".
I am with you on this one, because it was a total abuse of admin powers, and totally unfair. I've also been playing on this server for months, I've even got up to Rank no. 1, and have seen quite a lot of what I consider poor adminning on Alpha's Part. He constantly tells people to stop camping but as you said, as long as the objective is attempted within the time limit, they where is the problem? To be honest, I've seen him camp on a number of occasions, it seems like a 'do as I say and not as I do' scenario to me. Take the following scenario..
We're on T on Dust1, half the team never rush, so if we rush it means certain death. The CTs are armed with AWPs and M4s, and we have no money. The CTs are all rushing us, to get easy kills, so the only hope in hell we have of turning things around is to camp and try to soak them up before going to plant. What annoys me even more, is that on occasions when we have planted the bomb, the CTs make NO effort to diffuse (often to look after their ratio or AWPs) and the admin doesn't make a sound. They are patently not attempting to complete the objective and no body says a word about it. Then you have Alpha's obsession with giving everyone 16k and then removing the weapons that they can spend it on. I've never been a problem on the server and I've switched sides in the past to even the teams, which hardly anyone else does, but despite this, Alpha's wasn't exactly forthcoming in his explanation as to why my friend got banned.
On that note, he was getting abuse from some clan people on the opposite side, and he was only giving as good as he got. Why should he rush when he still has 2 minutes to complete his objective? Why should he rush when none of his team mates were rushing? How can MCG have this reputation of being a 'respectable and non-abusive' clan when they carry on at him like they did? I'm sorry but they are the ones who don't understand the point of the game, they were just getting miffed because he was killing them so often. If the admins to this server want more people to rush, they should reduce the time limit.
Anyway, this isn't worth the time and effort, because I doubt anything will be done about it. Alpha's response to me earlier suggested a 'if you don't like it, get stuffed' attitude, and it's never much good when he's on anyway.
