I would add what has been said in the Regarding Pictures thread, and that is that if you have posted a photo of yourself on THIS forum, that photo is fair game. If you haven't, the offending poster will have their post moved, edited, or deleted at the admins' discretion. People know what I look like, but they probably don't know what LotusBud or Oak look like because I've never seen them post their pictures.
Also, if you're having a problem with a particular member dropping hints about your PI, let one of the admins know and they'll be watched more closely.
