Something similar happened to me where my professional information was being dangled at me during debates. I contacted V and requested that the threads be deleted. They were and the party was warned. At the same time, I took screen shots and the communication exchange and shared with my attorney, he then advised me to contact the owner of this site with a very specific message, this has also been filed.
This should never have to be an issue on a message board, now that you mention the Mod, I am suspicious of his involvement as well.....
Shew...this post is really out there!
