Stormrage, have you considered contacting the person you suspect? There might be a way to do that ... an e-mail (so you can keep a copy) saying something like "I have reason to believe you're spreading misinformation about me ... let's talk this out as adults" or some such message. Even if they don't respond, that might intimidate them by indicating that you know who they are. You might include in your message something to the effect of "if libellous activity continues, I will retain power of attorney...(etc.)" As you know, you can't accuse unless you're certain. However, on an educated suspicion, it's reasonable to contact the suspected party in an attempt at resolution. Just be careful how you word it, if you do this. It couldn't hurt to seek free legal consultation on this sort of thing. An experienced attorney's advice would be worth a lot of peace of mind for you. Most lawyers consult for free the first time, so there's no loss, and perhaps a lot to be gained. My own lawyer once told me "if you hire me, we'll win, but your life will get worse for several months until then. Let it go and make the best of things." Most importantly, remember that people don't necessarily believe what they read from anonymous flamers. Look at all the love for you in this thread! Also, so long as you're honest, you don't have to justify the quality of your work. The buyer is always taking a chance with any purchase, and from what I see, your textures are great, anyway. I've bought disappointing things from the Marketplace (not from you,) but figured "oh well, that's how it goes" because there was nothing misrepresentitive in the ad copy. More often I'm very pleased with Marketplace items. Nobody should be complaining about free stuff! If this creepy person really is trying to damage your business via false claims, you almost certainly have a legal case, as the validity of libel charges hinge on damage done as a result of malice. If I were you I'd also solicit advice from whomever is in charge of Renderosity Marketplace. They'll almost certainly have some good suggestions. Best of luck to you, but don't stress out too much! You always win by taking the high road, and your good reputation probably can't be harmed by one anonymous loser.
