If your report in-game isn't immediately handled you can always record your evidence in the form of a video or screenshot(s) that can be used in a forum report. Use the
Ban Request template and fill out the questions with the appropriate information, then make a topic in the
Report Abuse section.
Either that, or you can report members of staff if you feel they are neglecting their position by using the
Demote Request format and making a thread in the same forum section.
Hope this helps.
