I know that, my point is that they don't have the tools to do anything other than defederation right now.
If any users from other instances than those two act in the same way and they happen to be from other big instances, they'd have to defederate those too, because they have no other tools available.
And they knew they won't have other tools availalbe when they created their instance, so they should've created such a platform in a place where they actualy had the tools to run it like they want.

Which would've been a classical forum in my view.
Like they want to have a community where they can proactively prevent people from posting offensive things.
That would be the ideal case for a forum where you have a manual registration proccess like they have now here. Because here their registration process doesn't help when you can just comment from another instance.

And had you been on an instance that was defederated you'd have to create another account to acces their community, just like a separate forum, which I exaplained in the other post would be the better choice.
Because it doesn't make sense to have that kind of manual approval registration system aimed to only have specific users in the community that share their values, so they clearly want to crontrol who can and cannot post there... and then being on a plattform where users can just join another instance or even create an instance for their own and then post what they want on beehaw and the only way to prevent this would be proactively blocking all other instances and working with a whitelist instead.
