An anonymous reader writes "Pages at ireport.com and extortionletterinfo.com have been documenting and researching the activities of George P. Riddick III, previously known for his lawsuits against IMSI and Xoom at the turn of the century. In 2007 he issued a largely-ignored press release claiming the majority of clip art online infringes a copyright and has ranted about how Microsoft and Google are stealing from him. In recent months, he's apparently made a business model of going after web site operators who were using clip art they believed to be legally licensed or public domain, telling them they're infringing clip art collections he hasn't offered commercially in years and making outrageous settlement demands. He seems to have tested the waters on this some years back, but emboldened by the passage of the PRO-IP act, he's gone aggro with it. A few dodgy anonyblogs had popped up to 'out' him as a copyright abuser, but these recent ireport.com and extortionletterinfo.com reports go much deeper in documenting and researching Riddick's recent one-man campaign to be the RIAA of clip art."
