If I was logged into several instances at once in the client and seeing the composite feed and then could choose instance when replying or posting (with some set default, like from: field in e-mail clients) lemmy.world could ban piracy all it wants and it’d still be in my feed without me having to leave it or change instances.
There should be an option to see all posts on our feed from all our instances. Then when commenting choose the instance from which the comment has to be posted.
