I think the admins on most MTA servers, are a little too happy too ban someone.
I am still pretty much a n00b in this game, I can kill someone etc... but I only know the basic rules. Like: no cheating, no modding you know the average stuff.
But then I get in a server and I "helikill" someone. Then I get banned with the message "No helikilling", I mean I am banned from one of the good few Dutch servers where I have low ping etc...
Without a warning or a kick first. The admins on this game are so n00b unfriendly.
On a side note, I also think a lot people cheat. But that's probably because the health shower is screwed!
