If the pictures have already been posted online, then they are public information and do not belong to the person in the picture. (This is why its never a good idea to post incriminating photos on Facebook)
SMM should be far more concerned with being sued for impersonating a military officer, or being sued by the Gracie organization for lying about his progress within their group. Not to mention his comments about young girls, this guy should be flagged immediately for being a potential rapist/molester.
On top of all that, if you are still worried about posting his photos, either post them by a gimmick account from a different IP address, or else have someone living outside of the USA post them.
