Here's an interesting question: what would you do about old accounts that likely changed hands where the former owner was a scammer but the new owner is just a shitposter?
How are you going to
know that? The only two pieces of information you give are negative, the second less negative than the first, but I don't know if he a scammer or not. Besides, I don't think we're going to see the case you raise because the person who had the account before will have enough red tags and people will have no reason to remove them if they left them in his profile in the first place. If the new owner is "only" a shitposter, do we have to remove the red tags? I don't see it. Besides, if he gets to join a signature campaign it will be 1xbit's. I think the case you make is too hypothetical.
The problem with the thread you link to, as with account sale cases in general, is that when you start to dig in you find that it was just the tip of the iceberg and there was a lot more shit going on underneath.
yahoo62278 opened that thread because he and others felt some empathy towards the protagonist of the story and his sobbing story, so common in these cases, and in the end it turns out that it was not only a bought account but that behind it there was ban evading and participation in the 1xBit campaign that we know of, and there are many things that we did not discover in this and other cases.
