I don't necessarily think it was OK "back then" in 2016 when I started tagging account sellers, but this was kind of a problem that was emerging.  It became clear to me at least that people here were starting to deal in accounts, and that led to shitposting account farmers, and that people were buying green-trusted accounts in order to scam or to shitpost with.  This crap was not immediately apparent to me when I joined in 2015 as far as I can recall.

So I tag account dealers.  There's a limit on how many deals I see going on, and how far back I'm going to go.  At this point I'm not about to start searching years-old threads to tag account dealers.  And I may miss some.  That 'inconsistency' may grind on some people, but think about how many crimes occur that don't ever get prosecuted.  We all learn to suck it up and move forward.
