Charles Carreon, the lawyer who sent a letter demanding $20,000 from The Oatmeal on behalf of FunnyJunk, is evidently his own worst enemy. First he threatens a lawsuit against Oatmeal creator Matthem Inman, claiming that Inman's complaints over Funnyjunk's users reposting material from his site constituted defamation. Yesterday, he expressed bewilderment at Inman's "tactic" of publicly making fun of his stupid legal threat. Now he's posted a notice to his site saying that he's taken down his contact information: "Due to security attacks instigated by Matt Inman, this function has been temporarily disabled."
I have seen no evidence that Inman instigated any "attacks"* -- security or otherwise. If Inman didn't instigate any attacks against Carreon, this strikes me as a highly defamatory thing to publish.
*Also, getting nasty emails is an "attack," but not a "security attack."
