Married guy encore

Well, married guy has written again, making it twice in 24 hours.

Hmmm I've got a feeling that there is a lot about you that is a wonder. What did you think about my profile? You look so familiar - I wonder if I have met you before?

I am tempted to respond with a "Dear Sir: I'm not interested in a clandestine and morally questionable encounter. Thank you for your interest." For now, though, I'm trying the whole ignoring thing since he's starting to creep me out. If he writes again, he's getting blocked. Persistence, in this instance, is extremely off-putting.
