I have never advocated this before, but I think it is time to consider having a "Sheer Stupidity" Zot, whereby someone is just so stupid that they get banned until they compose a 1000 word essay about how sorry they are that they tainted the forum with their stupidity, and that they would like to be allowed to post again.
We'd have to have a separate fund drive for the increased amps needed on a daily basis.
