"Guest, I also do not sign in sometimes to reply to someone so my name does sometimes state Guest Alison.

is a somewhat odd statement to make don't you think? There was no "sometimes" about it."

Guest, I have signed in sometimes, but this was only when I have pm someone because you have to be a member and be signed in to pm someone, and only that particular person would have seen my name during that time. I hope this explains things.
