You need to hire an attorney well versed in Cyber issues (you live in NorCal where because of silicon valley, there is no shortage of such talented attorneys). The attorney will likely start by sending this bozo a cease and desist letter, and he/she can advise you of the next best course of action.
We do not have an attorney-client relationship. I am not your lawyer. The statements I have made do not constitute legal advice. Any statements I have made are based upon the very limited facts you have presented, and under the premise that you will consult with a local attorney. This is not an attempt to solicit business. This disclaimer is in addition to any disclaimers that this website has made. I am only licensed in California.
