Here's just an idea....
Penalize excessive negging.
If someone uses more than 3-5 negs a day they automatically start shooting out gray reps.
Also, make negs automatically deduct from both the user that is getting negged and the person that is giving out the neg. Just make the percentages different (negs still has the same value before but the person that negs loses a smaller percentage of their rep)
Supporters should have more initial rep. Same with the more respected posters.
Mods (the neutral ones

) & Admins should have the most power to balance out any fukkery.
Ain't no stopping rep crews or boosting....:vince:
