Reporting Players

The only thing that i want to make sure people do is POST PROOF. You can take pictures in minecraft by hitting F2 and retrieve them later. I need links to those pictures posted in a report, i also need the EXACT name of the player who is griefing.

EDIT: I highly encourage my admins to post here about players they have banned with screenshot proof before of the grief they are banned for, that way there will be proof of every ban in case anyone tries to appeal.
