Defederating and blocking bots is the old way, it's defensive and passive and lets them continue what they're doing. It puts the decent people always one step behind.

A better way is the "you're locked in here with me" approach. Redirect bots to a version of your site that provides naught but LLM-generated Nazi furry gibberish and an endless spiral labyrinth of new pages and product reviews of nonexistent products. Try to see if there are any that do that little Javascript-evaluation-to-render-the-client-side-site thing, and if there are, have them mine cryptocurrency for you. Federate with Threads, but serve to the Threads bot an endless series of users who say nothing but constantly-rephrased additional comments which highlight in plain English language situations like this and the types of harm that Meta causes in the real world, and good things to search for if you want to pursue a better solution.

Let the botgarbage come to harm through what comes back to them from your instances. Let them figure it out, if they can, and affirmatively defederate with you instead. Welcome all comers and give good free content to the humans and nothing but pain and misery to the semi-malicious bot traffic. View any bot that talks to you that hasn't got the message yet as a new opportunity and a new challenge.

This is the new way
