Hey Sandeater,
If you feel your ban was not justified you can use the format linked below - the format helps our DarkRP Administration and Management Teams have all the important bits and pieces of information to review your ban properly!
As a note: You're welcomed to detail out how you feel the staff member improperly handled the sit; but the focus should be why you feel you didn't break any rules, and thusly, should not have been banned.
Hope this helps!
