Glad I'm not the only one leery of this whole DNF Verified thing, which is a farce anyways, since DNForum doesn't guarantee anything, and further disclaims all responsiblity for problems which invariably will arise.
I've found over the years that some scammers will operate relatively in the open using their real name, etc; forging a utility bill is so easy - and faxes ... who trusts a fax these days when people can "photoshop" whatever document they need and then send it directly via their computer fax modem or via one of the numerous on-line fax services.
It comes down to reputation, which is not something one can buy, but rather one must earn over time doing business.
