Fell for what?? They didn't say it's a dealers only web site and the guy from FOX was logging on from one of their personal computers.
Any way you look at it that's an unsettling warning screen. And it's not warning any dealer about using the site, it's warning any "user" accessing the site.
"Sort of" is such a harmless thing to say. "Sort of". It's just a filler. "Sort of" - It doesn't really mean anything. But after certain things, "sort of" means everything. Like after "I love you" or "You're going to live" or "It's a boy".
