I don't know what your personal issue are with him, but what he is doing is not right. If you did not scam anyone, then why is he doxxing you? Also, doxxing outside the investigations board is not right, and this is what Theymos says about it.
The reason that doxxing has been allowed up until now is that it's occasionally very useful in scam investigations. However, oftentimes doxxing someone is used as a weapon in itself instead of a part of any investigation, and as a result innocent people are sometimes hurt. So to protect the innocent while hopefully not hampering scam investigations too much, here are some new rules on doxxing:
1. Personal information must be confined to the new "investigations" board (under Scam Accusations), which is only visible to Members and above. Personal information is defined as anything which links a user's online identity (username, email, etc.) to their meatspace identity, excluding links that the person himself has posted. It is not allowed to post somebody's personal information in any other public place, including in signatures.
2. It is not allowed to post someone's dox if it is especially obvious that you're just using the dox as a weapon. For example, if there are no remotely-plausible trade complaints, then the person can't be a scammer, and their dox should not be posted.
3. As before, anything that the legacy insecure government/banking system requires to be secret is not allowed anywhere. This includes social security numbers, credit card numbers, and certain account numbers.
Maybe you can report the post to the mods so it's deleted or moved to the investigations board.
