Cartoonist Matthew Inman of the profane site "The Oatmeal" snarked at a for-profit site, "Funnyjunk," where users regularly plagiarized his work without credit. In response, Funnyjunk hired an attorney, Charles Carreon, who claimed Internet savviness; Carreon sent Inman a threatening letter demanding $20,000 in payment not to be sued for bad-mouthing Funnyjunk.
Inman responded by publicizing the letter and hosting a fundraiser to raise $20,000 for charity. It has already generated over $100,000. [Popehat; MSNBC; Randazza; more links at OL]
