Yes, even now I can get "lost" on exactly where I saw something, and I've noticed that trying to repost an "original" link to the source isn't always that easy to do, since I'm probably seeing the Kbin copy. I don't know what the correct etiquette is, or is it even matters as any comment they make on one should eventually get back to the other...probably.
The big flag is when you click on a link, such as from this listing, and find yourself on a page where you aren't signed in and it looks different. I'm not sure how that could be made more seamless without really over-complicating the whole thing.
I don’t know how exactly would that work and I don’t think that all links will be fixed (I didn’t look to deep into that) but at least they are working on fixing the issue.
Edit: oh, you are on kbin, then idk how would that work, the fediverse is a bit complicated xD
