For me, the question is what purposes do either list serve? Punitive, deterrent, vengeance, warning? Neither prevents the transgressor from transacting. It seems that the public shaming that occurs (either in the sales thread or in this forum) has more of an impact so maybe that's the purpose. To provide license to others to out someone (whether it is the seller who is/has been a bad actor, or the buyer who ignores the past (i.e., the cool book shaming). Personally, I avoid Sellers on the list or nominees (whether justifiably nominated or not), but it's not the list that alerts me. It is the discussion related to the list.
