They can file a complaint with Pay-pal, and we'll see what happens from there. We've all figured out not to deal with this scammer, there's nothing WE can do to get THEIR money back for THEM...there are steps they can take...filing with Pay-pal is the first step. They can also file a complaint with the Postmaster General, and also with the local police in the town where the turd lives. I believe there is even an internet crime website affiliated with the FBI where you can file a claim. They (the victims) need to take the necessary steps.
They are not the first to get scammed, and sadly, they won't be the last.
