Could be, for sure. I may try to post some things from Lemmy.ca to Kbin later. I was successful in posting from Kbin to Lemmy.ca a few hours ago, so I wonder if there’s a problem in the other direction.

UPDATE: I was able to successfully post an article to kbin.social from my lemmy.ca account. It did take about an hour for the article to show up on kbin (when not viewed from my lemmy.ca account), but it did eventually show up.
