I like the idea but at the same time I think it would create too much of a barrier for new people. If I had to jump through a bunch of hoops just to join it takes away from the (at least in my mind) purpose of LTBc. While it would help weed out some of the spam, all listeners should have an equal opportunity to get LTBc no matter how long they have been listening.
I think it is a delicate balance and whatever system is in place should not hinder people from wanting to be a part of the network. This is why I suggested offering LTBc as a reward for such a educational questionnaire, perhaps equivalent to what a person would have earned anyway in LTBc from posting junk posts. No matter what, I think incentivizing the right behavior is key, and completely agree with your points about wanting to create equal opportunities.
