Fandom #watchalongs work best if announced in advance in a public post with a special hashtag so that some can follow and others can block it.
If the first posts are public, then those who want to find it can. Then make later posts unlisted in a single thread.
If there was a macro to make it easy, that'd be nice. Otherwise, there should be a site where people can learn #fandomFedi best practices. (Thus the previous wiki discussion)
Our problem is just figuring out how to fan here.
