Is it ok to talk to this man who knows me but is staying anonymous?

There’s a man talking to me under an admittedly fake profile. He’s someone I know. From my past. Who wants to remain anonymous but be Facebook friends, he said. He knows mutual friends of mine and he is one of the aspie men I know. He could be any of half a dozen men. I’m bored and mildly curious.
