Me and a couple of friends always play on a server that my friend makes (one of the insta servers) i thought it would be nice to play a late April fools joke on them so i created a new profile separate from the one i use and named it "Password Stealer #4145" (i only used it on his server mind you" and he banned me (i know he would do it) so i said "April fools! now can you unban me?" and he said he doesn't know how to as he can't find the .txt file with the id's he bans
now i am perma banned from his own server. i can still join other severs just not his is there a ban.txt like the one in Arma 2?
