A long time ago (around 2001-2002 IIRC) there was a problem with people getting together to take over the top 20 all the time, and then it spilled over into some contests.  I think it was mostly isolated to Poser, but don't remember all the details anymore. 

As for winning contests... the closest I came was with my "Creepy" entry which either got 3rd or 4th place, but for some reason, nothing happened after that so I never learned if I did make the top three.  So for being here only a short time e-brink, you've created one heckuva portfolio which I always love to look at. :)  I consider you one of the artists I have to outdo to win any competition.  LOL

I'm definitely happy with the 321 voting system.
