A post on kbinMeta states that “Lemmy.ml is blocking all inbound ActivityPub requests from /kbin instances.” More details here, but the theory is that – rather than defederating – lemmy.ml returns a 403 ‘access denied’ message in response to any inbound requests from a user agent with “kbinBot” in the string. Upvotes, comments, and boosts don’t seem to be going through. However, it appears that lemmy.ml still federates information outbound to kbin instances.
I’m wondering if anyone here knows what is going on and why it might be happening? Federation between Lemmy instances and Kbin instances seems to be a selling point for both, so I’m sure others using both services are curious as to what’s going on.
Well, in case someone has the same idea, I just checked and the string kbinBot does not appear anywhere in the lemmy git repo.
I also must say the whole conspiracy nonsense in the comments over in that kbin link you posted really doesn’t look good for their user base. Most likely this is some sort of bug or compatibility problem.
