"This was not like a botnet-style DDoS," Woodcock told The Register. "This was a joejob where people were just clicking on links in email and the people clicking on the links were not malefactors. They were just the sort of idiots that click on links in email without knowing what they are." Joejobs are spam messages that are designed not to push Viagra but to induce someone to click on a link in the hopes of harming the site being linked to.
Seriously, people following links in spam messages could cause enough traffic to flood Facebook and/or Twitter? That sounds a little hard to believe that THAT much traffic could be generated by people suckered by spam, let alone that the level of traffic would be sustainable.
I would think that the amount of effort to send out enough spam messages to generate that traffic could have been redirected into just generating that traffic in the first place.
so facebook and twitter were taken down by a bunch of people hitting the same link once? that seems messed up, you would think big sites like that would have the infrastructure to handle something like that
