That is true, however registering domains isn't trivial or cheap.
So this wouldn't be something you could do en masse and therefore could be managble for admins to ban
Yeah, the cheapest ones are like 5€ per year. But to really spam the fediverse and make it impossible to block you, you'd need thousands of them. And that's not really worth it, it would be much easier to just create accounts on random instances, or spam normal social media.
Its not in any way.
There is nothing stopping someone from running up an instance and bombarding other instances with agents.
Sure you can block the instance but all it takes is a new domain registration and you are back to square 1.

They're way ahead of you, and most of those companies welcome bot activity, since it artificially inflates engagement metrics.
