Clicking that on Kbin gives me a 404 Not Found, clicking that on Lemmy works.

What I typed in was [!bunnies@lemmy.world](/c/bunnies@lemmy.world) which I got from the sidebar of Lemmy communities. I have had other people bring up the format with the exclamation point before, this is the first time I'm being told to put in what I see in the URL on Lemmy. I really wish people would just make the different linking methods compatible between Lemmy and Kbin, I always try to accommodate for both and somehow always end up with a comment telling me I did it wrong even though I try to listen and do what the comment says.
