That could work, but it would be terrible for discoverability. In the mean time, I put up a feature request at Lemmy. I’m not a fan of pushing my problems upstream, but in this case it would actually be the easiest solution - as far as I can see (and I have 0 experience with Rust) they only need to adjust the validation regex, because the database already allows for it. That is - as long as the ActivityPub protocol allows for it.
If they deny it, I could try something with name mapping, but you’d either end up with something that is unreadable, or something with a high collision chance. Neither option is very appealing. For now I’m just going to wait and see.
Unfortunately, Lemmy cannot handle community names over 20 characters, so this won’t be possible.
Can you somehow us a very short hash function in those cases?

AFAIK max username length on Mastodon is 50 characters. That should be a sensible limit that would allow keeping us interoperating with them.
I see the issue is closed, does that mean another request for this sub will work?
Yeah, I’ve upped the limit on this server, so it should come through now if you retry.
