but it seems like situation my situation B still violates the intent of the rule, which is to stop people from advertising personal items without being paid members and posting in the "for sale" forum. it just makes it so that the person who is selling is unknown, but the advertising is still there.
though i guess someone could probably make a good argument that if its fixed related and not a piece of junk, then it'll end up on the thread even without the seller secretly ghost-posting it.
