My take on the matter is that account sales shouldn't be allowed. But, its impossible to stop account sales, so the current policy of allowing it to happen in the open is better than pretending it doesn't exist and banning the handful of account buyers that are stupid enough to get caught. There is more harm in giving people false assurances that whoever they are dealing with is who they expected because people couldn't sell accounts or they'd be banned.

Here is the point that I cannot seem to understand about people and their perception of negative feedback. Why is a red mark because you bought an account that big of a deal? If someone leaves you negative feedback saying that you purchased an account, that only matters to people who care about account selling. Do people see a red mark and assume that means someone is a scammer?  I'm under the impression that people actually read other's feedback before deciding to trade with them. If someone bought an account in 2014 and thats the only red mark they have, who cares?

Feedback is just a place where you can place your opinion of a situation. Red means you think it warrants attention before trading with that person. If you read through the reference link and it says, "User A is a big dumb jerk who hurt my feelings when we were talking about politics" or, "This account was sold on (Insert Date) If you are expecting to deal with the person who owned this account before this date, you are not"  if you don't care about either of those things, you disregard the feedback and continue with the trade.

A red mark on someone's criminal record for failure to appear in court over unpaid parking tickets versus homicide are two different things when you are determining whether to meet with someone you met on Craigslist. Its the same as here. Let people leave negative feedback for whatever they'd like. If you can't stand the idea of trading with someone who makes baklava with sugar syrup rather than honey, and you feel the need to leave someone a negative over that, who cares? It'll only effect their potential sales from those that were expected honey anyway, and would end up unhappy if they ordered and didn't know.

The only negative feedback that is outright problematic is false claims. I don't mean people with a difference of opinion when I say false claims, I mean, people that claim someone did business with them them when they didn't.
