That will convice people. Some random throw away account, telling them they must do something.
The account has changed hands at least once, and we know who is likely going to be trolling me. Anyhow, #off-topic.
I disagree with it doing more harm than good. Let's take a look at 2016 [...]

I admit I have no numbers to back my argument which makes it pretty weak.
Neither do I. That's why I explicitly stated "I don't recall any (although I may have not been looking hard enough).", as I may be wrong. However, if we were to thoroughly examine the sold accounts that got marked over time (regardless of neutral or negative) you would be able to see that a very fair number of them were used to facilitate scams, spam and whatnot (not to mention *genuinely* looking manipulation, vote brigading, et al.). At least *some* of these could have been prevented/suppressed with negative ratings. Even if we were to play the devil's advocate, I'd still strongly advise neg. rating at least Hero and Legendary accounts that have been sold. Some people tend to trust them more based on their rank, even though this is wrong by all means.
