What would you do?

I didn't mean to post twice, my mistake. Thank you for the advice. If an admin can delete/move this..

Free legal advice is worth what you pay for it.

Don't entirely agree with Chayro, because truth is an absolute defense to a libel or slander suit, and there are jurisdictional issues - they likely have to sue you in your state and county. It depends on the nature of the "proof" you have, and how you came by it.

Spoken like a true non-lawyer. Truth is a defense you can use after you get sued. The idea is not to get sued in the first place. It's not what you don't know that hurts you - it's what you think you do know. Be careful. It's a dangerous world.

Chayro, I've practiced law for 33 years, so far.
