Facebook: Block Applications

I could be completely wrong with this, but when Facebook says prevents this application from retrieving any information about you, could that include the fact that you even exist? I say that because I’ve been getting three or four invitations for both “Human Pets” and “PetrolHeads” every day for the last few weeks now, and since blocking the applications I haven’t received any. What can I say, I’m a happier Facebookian for it.
