The Corbin Bleu thing has been a fascination for awhile, I think. I seem to remember a thread on SomethingAwful or 4chan or something years ago.
I am pretty convinced it was just an in-joke in some online community or even just a group of friends to make this perfectly-fine-but-completely-unremarkable actor on of the most famous people on Wikipedia. Like, some completely mundane actor immortal by making him one of the most ubiquitous pages on Wikipedia is pretty funny.
I honestly could see myself doing that if I had more friends.
