Definitely, I plan to integrate spoilers with ActivityPub. For now, it's just a Markdown change compatible with Lemmy - there were many requests for it, and it was quite cumbersome. I will start working on federation after finish the refactoring. I want to do this on the new codebase - I'm getting closer, but initially, I'm fully focused on instance moderation, which will enable the operation of a global moderation team. Later, things with lower priority will be gradually implemented.
