I couldn't really care, I suppose.
It's usually the case that "friends" online are people you'll never meet, who can turn on you in an instant, who can lie about their life or their identity or anything.
Even on GAG, I've had so-called friends just turn their back on me and stop communicating for no reason. It didn't bother me too much.1
