The attitude and way we approach this person needs to change. I agree with Nevermore. If the list's aren't working WE as a community need to adapt and share our knowledge.
It shouldn't be a case of - Let everyone fend for themselves. It isn't Yojoe's responsibility to bring Bobman to justice. However it is the responsibility of the community to lower the risk of new members getting fleeced.
If say for instance someone says Darth Vader everyone instantly know's who he is.. If Bobman was advertised or presented in such a way people would stay clear of him.
The tools and weapons we have at our disposal to bring Bobman to Justice are there. The solution is also there, but we do need to stick together as traders of this community.
