I've had similar things happen, not UAV related but x-wife related. It's best to put people who make public statements against you in place. Go for the throat or their pocketbook if you feel the need. You should contact your attorney at the very least and have an official letter written to her, telling her to stop. You actually have your proof in writing and "Defamation of Character" is a serious offence and easily squelched once your true self is known to all. To the length that she went to destroy your name, you should own her house or let her make payments to you. Prove your innocence to your community through her ill intentions. If you don't stand up for yourself, with all of your friends, then these things will continue and people will be talking about you behind your back and the attacks could get worse or become physical, especially in a small community. Honestly, you need to terminate this issue with extreme prejudice. Use the police, call them and notify them as to what has happened on the internet with her. They really help in cases like this.
