I think it's terrible how these groups take advantage of those looking for a simple arms length business transaction. Is there any non-violent way to combat these scammers such as last minute cancellations, wrong addresses etc? Granted I'm a big pussy but are there any real men out there that can retaliate in this manner? I used to find it so easy to pick out the scams - the ads were all the same - almost like it was an agreement with those in the know. Now it seems the ads are getting less obvious, at least a few of them.
