They changed the guidelines a few months back to allow linking to pages that files are on (it was announced), if the links are going to a page other than the one hosting the file that would, I think be a violation. They do not however allow linking to what they consider "competitor's" sites, and those who linked to 3-D arena were asked to remove the links, even though in some cases this was the only way they could offer the files as we host them right on site for those who needed it. As long as Poser City never opens a store then Roity will probably be ok with linking to them but according to the TOS they shouldn't allow linking to a log in page, ony the files page. So in this case it is an abuse IMHO
