I have few questions to the more experienced members here.
1) Sellers here generally use the rule that says 'No PL/HOS members'. How do you enforce this? Before completing every transaction do you go and search the buyer in the two lists?
2) Some sellers have an additional rule that they will not sell to anyone on their personal lists (beyond PL/HOS). How do you generally implement this? Let's say a person on your personal black list posts a "take" on your sales thread. Is that "take" not binding? Would you publicly post this information on your thread to nullify the "take"?
3) As a buyer, let's say I want to implement the personal rule 'No PL/HOS sellers'. Since being on a PL doesn't prevent someone from selling here, does the onus of verification rely on the buyer? If I post a "take" on a sales thread of a member on PL, and later want to rescind the "take" because of the discovery that they're on PL, would it be okay?
