If you have lost admin status from inactivity, I suggest speaking with your divisional leadership about reinstating it or figuring it out.
In this sort of situation, if you're having issue, it's certainly best to try joining Teamspeak and ask an admin to come in and deal with it. If no one is available, take screenshots and record chat logs, or a demo file, in order to give evidence against the infringing players.I believe doing @@ in chat also sends a message to admins, if I recall correctly (if anyone can clarify it would be great)
