ill also add that iceshrimp.net has mfm/markdown/html formatting support, as well as emoji reactions, and soon will support some of the pleroma api

How do I register an account with Iceshrimp.NET?
This is required to verify the operation.

[nellePoint]

invite or registration only depending on the instance. regardless itd be an api request (curl).

as far as my instance (limbo.town) it is invite only, so you could provide you with an invite (i can give you the entire curl request) if youd like.

there is a swagger ui at instance.tld/swagger as well for all iceshrimp.net instances.
