The Spoof's readers have been taking part in a protest against the US's new SOPA (Stop Online Piracy Act) legislation which is currently passing through the Senate. Other websites, such as Wikipedia, have taken themselves down for the day in order to protest against the act, because pirates are cool or something.
The Spoof's website owners lack the technical knowledge to replace the site with a protest notice, so instead potential readers are being asked not to view the site. The plan appears to be working, with the vast majority of internet users not looking at The Spoof at all.
Out of The Spoof's regular readers, one of them didn't look at the site yesterday, and the other one forgot.
As the protest went so well, internet users are encouraged to repeat the protest every day. The pirates must be stopped. Or helped. Or whatever the law is about. Who cares, just don't read The Spoof.
