I feel your pain. I remember those days back when I got excited for getting a daily award, but now it's pretty much a necessity to getting any exposure at all, not a bonus things. But regardless of what's going down with this one website, keep moving forward is all I can really say.

I think the staff are already doing as much as they can to improve the situation without implementing some sort of portal mod system. They already lay out an incentive of $100 a month to a random voter (though i think this number could be increased to one a week), and if they automated the system, or had mods approve flash, it wouldn't be newgrounds anymore. I feel your pain though, and all I can say is just keep posting to promote awareness of the problem. Get people interested.

Most days only one submission ends up getting blammed, it almost really negates the need for the blaming system.
