Does that mean you (as a non-global Mod) can see they're banned, but it might be a temporary ban so you can't tell for sure? Or does it mean you've listed all accounts that were last active before 2017?
The
former. I can't tell if it's a permanant ban.
The listed accounts are both banned and were last active prior to 2017 which means it's almost guaranteed that the bans are permanant, because it's very unlikely for an inactive user to get a ban (non-perma) for something he did a few years back.
