The impression I get is that Beehaw is trying to seclude itself not to be an echo chamber, but because an admin saw CP get posted and is traumatized by that, and it’s really highlighting the lack of mod tools. They want to moderate the space to ensure it’s nice (and it’s frankly needed. I made a Beehaw account at one point in time. I reported quite a few not-bigoted-but-still-nasty posts) and right now being federated with everyone makes it way too hard because even if 1% of posts are anywhere from “not nice” to “you literally posted child porn,” 1% of 100 is easy but 1% of 100,000 could be a lot of work.
