Global Banned for executing 1 script.

I'm a newbie here, and I'm not a leecher or anything, I've done hacking and scripting before on other games, and I tried out a script executor for DayZ like 10 seconds ago, tried to execute 1 script (I think vehicle spawn or god mode, one of those) in-game and it said I was globally banned. What I don't understand is, I had a bypasser that works and I didn't even use the damn script/hack, so instead of them just normally kicking me off, why did they have to global ban me? I'm sure I must have did something wrong, but is there a way to get myself unbanned? Any help is appreciated, thanks guys!

Also, will this ruin anything with my Steam stuff? Like will me getting globally banned like ruin my Arma2 game stuff on my Steam library or shit like that? Will it do anything to my Steam?

You did do something wrong. Link me to the bypasser you used, and it only dicks around with Arma 2, every thing else is fine.
