sorry for letting this through. I was really uncertain. Seems these spammers are improving on random text generation algorithms by now. I just wonder what for.
I read somewhere that a lot of that is to try and get addresses. Get back and actual response to the mail and chances are it was looked at by a human. Bump the address up to the verified level.
I'll let you know if my spam goes up :) Gmail is pretty darn good though.
