Mighty, I'm sorry you have someone reading your postings here. The best thing to do is disappear for a while and return under a new name. As for notifying the moderator...as I recall, anyone can view the forum w/o registering. This seems to be the norm for many of the forums in the cyber world. Yes, it would help a great deal if the forum was only available to those who log in and it would make it a bit safer...but you still would have those "lurkers" and/or "trolls" hanging around.
Mighty, if you are uncomfortable w/people in your real world reading your postings, change your forum name to something unique and don't post what your former user name was. We will find you.
As for the pesky guy, I agree w/Lifes Twists in confronting this guy w/a witness and just lay it out there that you are not interested in him or hooking up w/him. If you state you don't like him being pushy, he will take that to mean you like someone who is more subtle, etc. They don't hear what you are saying and the only way to shut them down is to say no/not interested and leave it be. The more you dance around the situation, the more determined he will be to have that contact w/you because he thinks that there is still hope.
I do hope that today is a better one for you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
