well.... i dont know if this is possible with Vbulletin or not, but i have an idea i just remembered
I used to moderate a forums like a year ago called Planet Community
www.planetcommunity.com
well anyways... they used to have an old system using Karma, im sure most of you know what this is
anyways if you were good and you did somthing great an admin,mod,security member might give you a karma... after like 200 posts if would go away, so its not so big of a deal
then if you spammed or went against the terms of service you would recieve negative karma
after you got so far in the negatives you would be banned or something...
please feel free to post any comments
