@grishka To me this suggests that you're using the wrong model for your storage.
I think that it's not specifically stated in the activitypub spec that Activities are immutable but the Objects that represent their side effects aren't. If you treat the Objects as immutable too you'll have a bad time.
@mariusor my implementation is much more straightforward than that lol. I just forgot to delete retoots when the original toot gets deleted. And I can't use the MySQL's built-in relations to do this automatically because I will be storing different kinds of references in the same table.
