No kidding.

If you're so concerned, then if it's not on github.com or not advertised via blog.github.com ... ignore it!

I mean, we're not talking about Phishing here. We're talking about a user who is annoyed that he stumbled upon a site and is unsure if he should like it or not. Almost sounds like an odd form of brand loyalty. "I can't decide if i should like this or not"

Really odd form of brand loyalty. "Things are diluting the brand I like, I'm going to switch to a competitor so I don't have to worry about liking things related to the brand I like"
