Yesterday, 2nd november 2014, i got permanently banned by MasteR without any warning. also, i got kicked 3 times before beeing banned.
ID:VALVE_0:0:787808286
MasteR,please explain why i got banned.
Whatever the reason... i am trully sorry.
I don't cheat, i hardlly say "strong language", what did i done wrong?
You must be thinking:"why do you use a Valve ID?"
I use a Valve ID because i cant run steam. Trully honest.
You think money grows on trees?  no it doesn't. (pay no attention to that line, it's about getting a new computer)
Anyway, thanks for reading. I hope that we can get into a understanding.

Oh, if i have some of my writing wrong... sorry. english it's not my primary language

I can confirm that he can't run Steam, a few days before the ban I asked for his Steam name and he said that his computer is too old to run it!

after the "updating steam" message is a BSOD. I tried Re-installing but still BSOD. Anyway... Thanks Elitesse!

[Master]

Your ban has been lifted.

You were banned because you do not use steam, and I was removing all nonsteam users from the server for a steam users only event.. I tend to do these things from time to time.
