I would suggest that FunnyJunk get themselves some competent legal counsel, because right now it doesn't satisfy DMCA 512. According to 17 USC § 512(c)(2), safe harbor protections "apply to a service provider only if the service provider has designated an agent to receive notifications of claimed infringement".

FunnyJunk LLC. need to provide these details "by making available through its service, including on its website in a location accessible to the public". They need to provide at least "the name, address, phone number, and electronic mail address of the agent".

And I'm sorry, but the webform at http://www.funnyjunk.com/copyright/ doesn't do this. I can assure you, that there is absolutely no way to transmit a physical or electronic signature as they have stated on their page via their form.
