Yeah, this is terribly easy to fake. Also, if you look closely, they repeat a lot of the same e-mail addresses with different "real" names attached to them. e.g., flyman@gmail.com and kidrock@msn.com (which appears right next to each other...)

I noticed it too. But it does not quite make sense, because nobody likes to sign up twice using different email address immediately, even if they don't remember their password. This reminds me that the exposed the data might be fake too.
