I think you're on the right track keeping out the people who just post to sell and dissapear.
I'm knew here, have nothing to sell but I would like to see what's for sale. Can you limit posting only? That way everyone can shop in the classifieds, but only 50+ can sell.
I'm not answering for Bruce (or js), but I'll give it a shot.
The reasoning for not being able to view the classifieds is probably because you could then PM the seller and try to initiate a sale. If you are a newer member, this can more often lead to a bad deal than if you were not.
