Too scared of being Rickrolled that you need a way to determine the threat a site poses? Enter RickProof, which will gauge the entered URL’s probability of said action, and warn you against it, if so.
I’m not sure how accurate it is, to be honest – I entered Tech Digest’s URL and it claimed we pose just a ‘minimal risk’, even though for the entirety of the morning of April Fool’s Day, every outgoing link on this site was a Rickroll. Perhaps the site’s creator is as much a fan of Rickrolling as I am – I just set up a Facebook group for people who actually enjoy being Rickrolled. Feel free to join here!
