Yeah, I think there needs to be a change to this. If the seller/buyer holds a grudge for the other person not paying/going through with a deal, there is almost no chance for redemption and removal from the thread, because the offended person will probably never accept their apologies.
I really don't care if you're on the list or not. Everybody on here knows you inquire about books, offer to buy books and then pull the let me think about it and never respond back after the fact. I don't see you taking any responsibility at all, just the same old same old
