I think this is the best answer yet!

After a while bitching about a problem just turns into background noise. I love solutions!
I could expand on this a bit.
They could "level" their way up.
Level one=SOC entry.
After X number of wins in SOC structured games earns Level two.
Level two: They earn the right to JOIN
certain community Games.
Level three:After X number of wins they earn the right to JOIN
any community games.
Level four: After X number of wins they earn the right to CREATE games. still limited to less complicated maps.
After X number of wins on different maps (think mini crossmaps) against X number of unique opponents they earn full site use.
Hell, they could be awarded a medal for earning each milestone.
Everyone who has ever played Video or computer games understands "unlocking" new aspects of the game and the sense of achievement that comes from reaching a goal usually keeps people engaged longer.
In keeping with the "military" ranking system. The SOC could be renamed the CC Boot camp. Within the beginning stages of the "training" all the problematic rules and the layout of the forums could be explained. It would engage people a hell of a lot more than just throwing them in the deep end of the pool and hoping some asshole doesnt do a cannonball on their heads.
This,
in my opinion, would eliminate farming and reduce the number of multis. This in turn would lead to less work for the multi hunters so they could actually have the time to screen the new recruits for multi accounts. Which would in turn lead to more credibility for the MH's, which has apparently taken some hits lately. (just an observation)
All of these things should improve the site competition, the site moral and force some to find new things to complain about.
