If your policy is to publicly shame with full name, address, email, and phone of those that you consider to have scammed you, please update your privacy policy to detail exactly the circumstances in which you're going to do this.  Your current privacy policy explicitly says "We will not disclose or sell your personal contact information to any third parties without your permission".

But I really wish that you would reconsider this policy:

• The name and address provided could have been someone else's and now you're publicly posting it
• It could have been some underage kid who stupidly did this and now you're posting all of their info
• As encountered on sites like Reddit, people can go on internet witch hunts with people's private info - possibly against the wrong person just because they happened to find someone with the same name on Facebook
• Do you really want the privacy-conscious Bitcoin community to have to stop and consider the possibility that ALL of their info could be released on the forums before making a purchase?

I sympathize with the fact that this guy isn't returning the excess Bitcoin, but posting _all_ of their info publicly is a bit extreme to me - and completely against your current privacy policy.
