meh, I think a minimum word requirement, or perhaps a limit as to how long after you start a game before commenting would be far more effective, especially to keep the people who just rate/comment each game for the AP without playing them from being able to do so quite so quickly. Obviously no matter what methods you employ people will find a way around them though.
I think that the minimum word requirement could work but it needs to be analized and thougth trough.Even so I agree with you in the point that people who just wants to get points will still find ways to do it and good posts will get buried under piles of spam.
