I would definitely file a police report. This is a form of identity theft, and the more reports they have the better they will learn how to help with it. Plus, should anything in the future occur, it will look bad if you hadn't reported this (then) previous problem to the police. Yes, definitely report it...keep a copy and note the case number. These things can come back to haunt you.

I'm sorry you've been subject to such malicious behavior. Even if it was some naive teenager or juvenile adult, it is harmful and mean spirited, imo.

You might take on another email addy/name and use it extensively instead. That way, you can show that you took different steps to overcoming this event? IDK... perhaps your webmaster coach can help with better ideas.
