This week, a mysterious website counting down to an "October Surprise" document drop that would change the election sparked frenzied speculation. Yesterday, the site was taken down after Politicker and others identified some of the developers who were behind it and connected them to past internet activity including a massive 2007 hoax prank involving a site that promised the release of  a new Radiohead album and instead "Rickrolled" visitors by giving them a link to the video for Rick Astley's 1987 song "Never Gonna Give You Up." In a note posted on "October Surprise" last night, the site's creators admitted that, rather than releasing explosive documents, they were planning to Rickroll people yet again.

"Sorry folks. Did NOT expect this level of interest. Apologies! Jokes! Vote! Sorry for the most predictable rick roll ever," the note on the site said.

Prior to the big admission, one of the developers who worked on the site told us it had been visited by over 100,000 people. The "October Surprise" Twitter feed is still active and posted a series of messages about the prank.

"there are no documents. or surprises in store. at least from us," one of the tweets said.
