(I suppose there'd be too many implications involved in doing it, like classifying reports as frivolous, individual banning from posting in a forum and remembering to unban them because the Admins have a lot of work, etc.)
I can see the 'more work less play' annoyance, and I concur, but the admins must have a shed load of paperwork without this system. It may add a bit more paperwork, but it may cut down on sanction spammers or useless/no evidence reports.
Rule lawyers will be stunned, and admins and community may be happier. Some may argue this will turn Disco into a sort of 'Nanny' server, but I'd rather RP while remembering the rules, than break them and leave the server.
