Can anyone who works with #ActivityPub please help with a question?
Are there limitations to what usernames can contain?
I have a #WordPress site with the ActivityPub plugin and a user signed up with a name that is just one letter and then two dots, eg “A..” but it seems to break their ActivityPub integration.
I’m looking into adding rules for usernames but would like to know the full rule set (a regex would be amazing)
Thanks! #mastodon
