It's generally been my impression that any user daring to leave a negative review is likely to banned from Renderosity as well as other repercussions(at other sites even). I know that even posting this message I figure I'll be punished in someway or another. As a result I never review any products I can't give 100% recommendation to. It's not worth the risks. It also means I tend to discount the reviews on products greatly, since anything negative is almost always contested by the merchant and then removed. The big problem may be the second line of your "unacceptable reviews". Any problems with the product are seen as "technical support" and not valid for complaint. On the other hand some merchants here go above and beyond to fix problems. I reported a problem with Batlab's A3 conversion of the Schoolgirl outfit and he responded with a fix up in about an hour. This being something he added as a bonus to the product in the first place. Lately I've been considering posting full length reviews of Renderosity products at another Poser site just because it's the only way I might be able to do it without being banned from here. I'd have to do this using a fake name, which I hate. Some of these products aren't so hot and it would be nice if people could tell you about them before you spend money on them.
