If I recall correctly, the main reason we defederated from those instances at the time was the sheer volume of spam we were getting from users of those instances. While we do sometimes have a need to moderate users from larger instances like Lemm.ee, it's not currently at a volume that we can't handle, from what I've seen.

As always, as a moderator of several Beehaw communities, I would encourage you to report any comment or post you see that isn't up to the standards of Beehaw.org. Don't assume someone else is going to do it, and don't assume that moderators are always watching every interactions closely - we're all doing this in our free time and have other responsibilities. We may not take action on every report - sometimes things are borderline or the community has already pushed back and we feel like things are in hand - but I guarantee someone is looking at and considering every one.
