Best way to make members aware of someone ripping people off in trading section?

Just to clarify -- that was a month ago when I was first alerted to the issue.
Joey, I thought I'd go ahead and search the forum again for my bezel that I need and I noticed 340swinger70 still has items listed for sale. Maybe admin could try to contact him and put him on "notice" that if he doesn't respond to admin's requests within a set time frame then his posts will be pulled from the site and possibly his account frozen or something? I would hope that other potential buyers would read his feedback reviews before venturing into any agreements with him, but at least it would protect other users if it was possible to remove his trading posts. Ultimately I too hope he steps up and takes care of business and I will do my absolute best to keep everyone informed if I do hear back from him. Until then there's nothing more I can do...except find another part and hope the next deal turns out better.
