Scratch

What do you mean? One day they were there, and the next day they weren't?
Other than a glitch, the only possible explanation I can think of is that they were inappropriate and were taken down. But I'd have thought the Scratch Team would've left you a message if that was the case 
I'd recommend contacting the Scratch Team directly, to find out whether it was in fact removed, or whether you were the victim of a very serious glitch. You can contact them here
