In fairness, I kinda get it for any small instances, Hexbear federation typically means a lot of arguments with libs, and that can be a big burden on moderation no matter your politics. All the love to our blind comrades though.
And honestly, I can't blame any non-general instance for defederating when a sizable bunch of users are very trigger-happy with spamming PPB on other instances.
I can. If you're a non-general instance and you're not somehow politically oriented like with a news comm or whatever I think Hexbear federation is unlikely to pose that much of an issue
