I think that Renderosity should send an e-mail to poeple who ahven't logged in for a year...ask if they want to keep their account. If they don't click the yes link, delete their account and all their images (but not forumn posts). As for gallery images, I normally hang out in the Maya part of renderosity, and we barely even get 2 a day, so its not a porblem here. And I barely post an image every week....
