This sounds like the kind of thing that can needlessly create misunderstandings.
I'm sure it's on the roadmap.
A kbin user asked me to DM them and I haven’t received a reply so as of right now I’m assuming no.
Based on issues #163, #633, and #1051, kbin currently doesn't support messaging between different instances, which will automatically mean kbin lt;- lemmy won't work. I imagine at some point in the future it'll probably get worked on though.
I didn't know kbin supported direct messaging at all. I'll have to remember that.
The short answer is no but the longer answer for what happens in each situation was detailed here: https://codeberg.org/Kbin/kbin-core/issues/1051
