It's very easy to create a Facebook account and Facebook page. That's why celebrity and personality pages have to be confirmed whether it's the "Official Page" or not.
Checking out Jose Rizal on Facebook, and you'd end up with lots of Jose Rizal search results.
Here's one Jose Rizal page with 27,554 likes. I guess this is what his page would look like if he were alive and on Facebook.

Note: The Twitter hashtag for Rizal from now til his 150th birth anniversary on June 19, 2011 is #Rizal150.
