I try my best to keep the server under control. I'm sorry that theres a ton of freekillers I can't control what people do on my server when i'm offline and I don't want half the people who play my server to be Admin.
The moderator mod is NOT sufficient administration for a Jail RP server and you should:
1) Change all moderators to admin.
2) Less player slots, like ten, since even then that's too much rage from freekilling.
3) Have more admins based on how responsible they are and how frequently they come to your server. Get rid of FrostBite, he's a known badmin.
4) Design your jails strategically to prevent frequent freekilling. If you can't think logically to do this, please don't host a jail RP.
