This guy claims to sell Special Forces Training Certificates.
There’s only a few problems with them: they don’t look like the real ones (in most cases, they look radically different). They never have the right names or signature blocks. In some cases, they’re for nonexistent schools or schools that never issued a diploma. In other cases, he misrepresents what the school teaches, probably because he has no freaking idea. Some of these bogus certificates are not even on the right size paper.
In other words, they’re bogus and it should be immediately obvious to anyone who isn’t a phony that they’re bogus.
So who buys from this asshat?
Wannabes and phonies, that’s who.
Never trust documents supplied by an individual, especially one who tells cinematic-sounding tales of derring-do (they’re cinematic because he absorbed them with his ass in a theater seat). Get him to sign SF180 and get your own copy of his records. If he won’t sign the form, request the publicly-releasable information on your own. Schools, awards and decorations, assignments are all publicly releasable, and ask for them specifically.
