It does seem like a fun idea, but I think we need to take this further (in light of the recent self-nominations). And so, I am proud to suggest:

I'm a JCF Member - Get Me Out of Here!

It's simple - each week a dozen or so active members get nominated. We all vote for them, and the one with the lowest votes gets kicked out. This would work wonders against spammers/flamers/trolls. Heck, I'll even write the code for this.
