Thanks for bringing this to my attention. I wasn't aware of this limitation in kbin. I made a post about spoiler best practices in light of this. I am not a mod in this community, but I would imagine that similar guidelines would be acceptable here given the complications of federating different platforms.

Nor in some Lemmy clients (like Voyager), hopefully spoiler support would get better over time.

In addition, kbin does not federate posts posted by bots (currently), so !episode_discussion@ani.social appears empty on kbin.social even though they are federated. You'll need to use an account on a Lemmy instance to participate there at this time, unfortunately.

Exactly what I was thinking about 😭
