Carreon has a trademark on his own name, when used for legal services, so when he sued Matthew Inman, donation collection site Indiegogo, the National Wildlife Federation, and the American Cancer Society .
Suing the American Cancer Society is pretty lame too. So, good luck with that. Let us know how it works out for you.
edit: see also. Carreon may well be correct that FunnyJunk can claim DMCA safe-harbor protection from liability for infringing user-generated postings on its site… but that doesn’t mean those posts don’t infringe on Oatmeal’s copyright.
