I've run into a number of scammers here, typically when I post a "Wanted" ad in the Classifieds. Their writing is very good and they come across as real legitimate members. However, the one thing that always hangs them up is photos of the item in question. They ALWAYS use recycled photos from Google or this forum. So, a simple reverse image search on Google will make it very clear whether or not the person is a legit or not. Highly recommend doing it if you're speaking to someone in question.
Posting a Wanted Ad here on Mud (and most forums) is like throwing chum in the water. Scammers and scumbag flippers are out there just waiting....
I like that @woody has put up a reminder banner.
