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.
I like the people, so don’t want to block them. And yes, there are tons of libraries for conversions, but would be easier to contribute to my app of choice to show “username” instead of “display name”.
