Nostr could be the most middle-of-the-road platform in terms of content and you would STILL be able to find all sort of outrageous claims about it on Google and any corporate-run platforms which have a vested interested in demonizing and limiting any other platforms that stand to get in the way of their business and propaganda machines.
The way to 'combat' bad ideas is to challenge them through discussion, not predetermining what is or isn't "hateful" content using AI trained on ones own biases and definitions with the hopes of shaping someone else's experiences.
I'm all for providing better tools, but I don't agree that this is one of them.
