Edit:
This is related to this bug: https://github.com/Memmy-App/memmy/issues/170
I guess what I need to do is completely filter out anything that is local. Super weird issue and frankly annoying that they can even be posted to Lemmy.
To test this, visit my profile and hit "Posts". I posted something in /c/test with an internal IP for reference.
Edit: We'll add some information to the dialog asking you to deny the permission and I'll do my best to filter these out so it doesn't pop up at all.
Edit: Fixed this now. See these commits for changes:
