OP is on reddthat (@falcoignis@reddthat.com), which is a Lemmy instance, and the community this post is on is !linux@lemmy.ml. Not sure what’s up with kbin appearing next to OP’s name for you, might be incidental because of kbin’s UI or something.

Edit: just looked on kbin for myself, no idea what is up with that honestly, but I see what you’re talking about as well.
