You learn to recognize the names of active users that post in threads you're interested in. I shouldn't be able to ditch that recognition but keep my karma, and you shouldn't have to look through my history to see if I'm someone you previously recognized.
Eh, maybe I don't see it. I mean, I use a lot of internet forums running scripts like XenForo and IPB, and those let you change your 'display name' whenever the hell you like. Yet I still recognise everyone perfectly fine. There are people on my forums that change their display name, avatar and signature on a weekly basis. I still recognise them just fine.
Same works on Discord too. There you can change your name whenever the hell you feel like it. Again, doesn't stop most people recognising you.
