This idea that everyone should be required to listen to the ravings of anyone passing by (or, on Twitter, anyone who has paid Elon Musk for the privilege) is really pretty weird. Mass blocklists are hardly new; “here are the people to add to your killfile to get some semblance of signal to noise” was a thing on USENET in the 90s, say, and of course, before Musk broke it, they were common on Twitter as an informal user-added feature (the death of the API made them far more difficult to implement.)
