Actually the prohibition extends 'way beyond trading in just OBJ files - it extends to trading in ANY commercial product, in whole or in part. And, by extension, no linking to or spreading of info about any WAREZ sites, or file-sharing software that allows access to WAREZ. Even the free stuff postings have to be either 100% original work by the member posting it, or accompanied by authorization from all original creators. In the margin of every page - under the "Renderosity" heading is a link to "Terms of Service" (Usually referred to as TOS). The TOS are the rules established for the whole Renderosity membership. There are a few "grey areas" members occasionally gripe or argue about, and sometimes they're changed/updated, but the Anti-WAREZ rules are pretty much an absolute. All members are expected to be familiar with the TOS. If anyone does post such a request there's usually an informal competition for as many members as possible to post in the thread making fun of them before a Forum Moderator or Administrator steps in to delete posts, lock threads, or Bann as they feel necessary. As I mentioned above, any errors involving missing files, just post the details here, and you'll get pointed to where to buy any products necessary, or (in some instances) where it may be an additional free download somewhere that you're missing (a lot of VERY generous people post really terrific things from time to time).
