This has been in my head for months that one big problem with the fediverse is that you can get linked for a fediverse service but to an instance your not on and you have to find your instance and hope it’s federated to the account your looking for.
I did run into this problem when I made a peertube plug in and I wanted to like videos but I had to paste in an instance just to get 404 error.
Plug in already exist, but if not it might be useful to make it
PieFed has this out of the box. You click a link at your home instance once on the browser you use. After that, you can get from any post on an unknown instance to yours by adding a few letters in the front of the URL on that browser.
