One thing you could do, if you have a serious concern about one of your own images, is ask the mods to take a look at it. It would be nice if folks didn't overwhelm us with such requests, mind you, but we really do want to work with you to make this the kind of community that reflects both Renderosity's mission and members' wants and needs. As for Liftan, my recollection is that he was banned for trolling the forums. And he will continue to be each and every time he reappears.
