Do you use a form letter to make first contact?

A guy wants to be my friend because he likes my About Me- which is blank. I suppose he's better than that other guy who wants to be my friend. All of his posts are about exposing 'fake' girls. Or the girl wondering if it's okay for a white girl to like big black c----. What a winner. I'm tempted to write back sarcastic responses, but I feel it's best to not give them encouragement and ammunition.
