Lots of words but all of it stuff we've known for about a year. If you want to get foreign offers through just redirect to the landing page until they approve it and then switch it to the affiliate link...not exactly groundbreaking.
When you say to just find legit offers to promote that nobody's thought of yet...that's what we've been doing for a year. You find something legit and run it till they decide it's not legit anymore. Again, not groundbreaking.
Sounds like you talked to one of their sales guys who, unfortunately, have no control over the approval process, and are not involved in it at all. In fact, they need to wait days just to get answers from the approval team. I wouldn't take what they say too seriously. The only opinions that matter are the approval team, and the only way to know those opinions are by submitting ads till you get shit through.
