It's what you deserve, cuty. I know you, you're from GSF server, aren't you? If you find out there's someone verbally abusing you, you choose to ban that person. People should tell you how to react.
Truly, banning is like;
"Ha, I'm forbidding you to play, can you get around it?"
The person replies with:
"Oh yes I can, bye server" and it crashes. It's what ESF is all about. If you would stop acting like a total *** and just accept the fact that some people just rape you, we're all cool. Banning is asking for someone to return. I mean, look at it. You're banning alot of IDs, other users might want to use someday. What purpose? Just so satisfy your own, selfish needs? Changing a CD-Key isn't hard, you change it and crash the server, banlist erased, player's happy again.
If you don't act like a *** at your own, hosted server, people will appreciate that and just play. Without those servers, noone could play, right? Means they are grateful for you to host. But don't demand anything like "I don't allow anyone better than myself."
GSF is a public server, so yes, there's difference.
Enough about you, about the banning stuff;
Do you think Devil would keep crashing if you'd do nothing? It's banning and flaming that enjoys them. Just think straight, you wouldn't be crashing a server just because you feel like it, it either has *** players or a *** admin. It has a reason, mostly because of the admin.
If you would stop banning, they'd stop crashing, it's easy math.
But of course, you can also keep banning and hope they don't return, which they will, for sure.
Speaking out of experience here, sue me.
