Looking at those twitter links, it seems that, perhaps unsurprisingly, the retarded conspiracy theory idea seems to have actually gained traction. Sure, guys, a middling-to-big 'net infrastructure company is running a protection racket against a furry porn site. It couldn't be that they, you know, actually *do research* about botnet activity and figured it out from what their test lab machines are doing, oh no. Verisign actually sell a decent product, though it's hideously expensive, and thus very far outside FA's realm of possibility.
Also, aren't FA supposed to be getting a sweetheart deal for bandwidth from their rack space provider? If they're pulling down decently-sized DDoS attacks on a regular basis, I can't imagine that arrangement will last long...
