Nah, ignoring them doesn't work past a certain point. If it did, it would have worked with Internet trolls back in the 90s.
You don't want to give small time versions of Musk or Trump a platform. That's when ignoring them works. Weird ass flat earther channel with 12 subscribers? Maybe don't post them on Xhitter as outrage porn; just let it be. Once they have a hundred thousand subscribers, though, you can no longer ignore them and hope they go away. If you try, they will yell louder.
