Hi @julian,
as long as nobody cares about the according standards, the #fediverse will be a brittle nerd niche.
The according standard is IMO https://www.rfc-editor.org/rfc/rfc7565.html#%3A%5C%7E%3Atext=userpart ( #RFC7033 and #RFC7565 ) referring to https://www.rfc-editor.org/rfc/rfc7564#section-4.2.1.
What you find in the wild, however, is a different story as thee is no agreed upon #validator service nowhere.
Hi @kichae,
fun with RTL. How is it supposed to be?
