yesitis3, UF formulas in the Public Formula Database are free to use for the purpose of creating artwork; no one (other than individual formula authors referring to their own formulas) has ever said people can do whatever they want with them -- for instance, slice and dice and mix and match bits and pieces to make "new" formulas and upload them to the Database, or copyright the default image generated by a formula, etc. -- without first obtaining permission to do so. Some formula authors have adopted the Creative Commons License approach to their formulas, but that can still impose restrictions on exactly what can be done with them beyond using them to generate artwork.

As a general note, I'd be curious to know what people consider "being harrassed" as used in this thread to mean; as far as I know, Renderosity's TOS forbids harrassment of members, so it's rather a serious accusation to make.
