I am a FragMaster member, not an admin.....
Post your grevances in our forums (
www.fragmaster.net) and the admin's will find out what's going on...
As for auto-banning, our server doesn't auto-ban anyone... we have a system where if you type specific words you get repies (if you say "Hi" you will get a welcome message, if you swear you will be asked not to swear), this is to keep the server polite, it's a public server and children use it so we like the language to be kept clean!
It is possible you were vote banned, not sure how long this last's on our servers....
But if you post in our forums, a resolution will be sought quickly!
