To be clear, some really great community members have these names, but they’re everywhere now. And with the right characters you can create some really annoying overlaps: https://github.com/LemmyNet/lemmy/issues/3790
Enough of them floating around now that I’ll probably do a PR for my favorite client to filter them out.
You’re missing the point. There are people who want to solve this problem (certain problematic display names abusing nonstandard unicode) without ruining display names entirely as a feature. I don’t care if you want to see display names or not.
