I am just catching up with this thread. Let me see if I understand. Someone stold YOUR puppies' pictures from YT and then posted the pic as puppies for sale. The dummies then contacted YOU about buying the pups?
In a nutshell, am I understanding? Geez, they must be some of the dumbest criminals around, but the sad thing is many honest trusting folk would see a "good deal" and send $$.
I have a motto: If it sounds too good to be true, then it probably is.

Way to go in your efforts to stop these thugs from preying on any more innocent folks who are in need of a furkid.
