@alice@Amelia@luna Well firefish post import "works" it has a lot of flaws hinting to the reason it's marked as experimental like it being able to just crash the instance, doing posts in weird orders, spam notifications of every user ever mentioned in posts and forgetting posts.
When I went about adding post importing for *key, mastodon/akkoma/pleroma, instagram and twitter I made a special function just so it doesn't have the ability to do all the spam related stuff as well as ripping out the federation of the posts to all other instances making remote users not get spammed by notifications which is also the primary cause of it being able to crash the instance the user is importing on. (ofc people can obv still see the posts if they fetch the note)
