"Global blocks are technical actions performed to prevent an IP address or range of IP addresses from editing all Wikimedia wikis, for a fixed period of time or indefinitely. Global blocks disable account creation from the blocked IP by default, and can also prevent editing while logged in to an account."
I use Britannica for anything that isn't celebrity/pop culture based now, I thought Wikipedia had killed off "proper" dictionaries but they're going in reverse. I enjoy the irony of that.
That doesn't seem all that unviable, at least specifically for Apple Private Relay IP ranges, is my point.
Much easier to simply block posts/puts to certain paths from ip ranges in the ingress layer, before they ever reach the application and are authenticated.
