In order to block that, every single admin on every single instance would have to set up blocking tools. From there, anyone that decides to start their own instance would have to decide to also set up those tools. Thats the main draw of the fediverse, you cant block anything because someone can always federate with an instance that doesnt have that thing blocked.
How would that possibly be enforced
Moderation and/or bots? That wouldn’t be hard at all.

It’s not my fault that you can’t understand the idea of general agreement vs strict requirement enforced with an iron fist.
