Dean Roellke has just confirmed exclusively to madsvassarblog.com that the admin Twitter accounts are "all hoaxes." He wasn't clear yet if the real administration will respond to the fake accounts or if they'll let the pranksters have their fun.
"The twitter account assigned to me is a hoax," Dean Roellke tells Mads. "I assume the same is true for the rest."
Update: Plus, we just realized the pranksters spelled "roelke" wrong.
Update 2: Looks like they corrected the spelling. Working link here. We also noticed that all of the accounts have disabled the "message" feature.
