That's where you're wrong. Sure, PBS gets secretive every now and then, but when it comes to digital series's or franchises, they don't care. I don't even think they know you revealed them. They were probably part of GO, and PBS just did some cleaning up.

Evidence: lots of Halloween and winter themed sites were revealed that were not part of GO, and were from 2008. But they weren't deleted. Same with Valentine's.
