Yeah, buyers fate in God's hands. Checking Jr.VIP membership duration, post counts, ratings don't mean that person cannot change suddenly. Am i right, my friend? As Vinku said above, there's a lot of shit list threads going against for jr VIP members. People are always changing, let's say a Jr. VIP member needs some urgent cash, and what he is choosing scam a buyer with a one-time fee. Suppose that the selling amount is 10x times larger than Jr.VIP membership fee he doesn't care he lose his membership or not. We can't go to international police to complain about 500$ scam in the forum? IDK if this will happen or not. It's just a thought that came into my mind.
As you said, buyers have to use their brains. But I like it if we can introduce a middle man service for that quick [WTS] purchasing, selling process. We can use all the moderators as the middlemen. Let's say we can choose a moderator as our middle man. He will get some percentage from the service or product at a one-time sale, and he can also check the product with the minimum waiting time. He can check the quality too. Buyers happy, the seller is comfortable also. And also, the BHW gets more income. It's just an idea IDK it's possible or not.
Finally this all decisions need to take from the authority. I'm just sharing my thoughts here. thanks.
