Theres no valid reason for you not tell the rest of the members of this forum who that person is. Just a heads up even. All my experiences buying and selling parts here have been nothing but positive, i would hate for someone here or me to get played by some random moron. if the guy cleaned up his act and decided to become less of a piece of crap, then he will just have to deal with people being skeptical of him until he earns that trust that he lost by being a bottom of the barrel individual. If the community and the forum have helped you even once, the least you can do is warn them about a bad apple in the community, just so they can keep an eye out for them.
