Both balt names have been banned, the supposed good one for feedback fraud, and bad one for posting porn, a typical way for them to "get rid of the name": http://www.pbnation.com/showthread.php?t=2619444
You should post up the person's name, city and state. Don't post up any more info than that. I think that railz has a pretty good database of scammers, so it would be easy for him to check it to see if it corresponds with any other scammers.
I am pretty sure that this person has been doing this for a bit. There are a few names that stand out:
These names have posted feedback for each other, as well as "baltimorenightmare". One other person that posted feedback, and seems like he is legit is ShreveportPball, as he left negative for a couple of them. Even if they are different people, they are all in the same area.
File the police reports now. Get as much info from each other, and then contact your local police departments, then everyone contact and deal with the same person from his local police department. Get in contact with ShreveportPball as well.
