I do think I should be able to post something publicly and not have it indexed by search engines. If someone screencaps it or copy/pastes it fine but the original should live on the dark web.

This is one of those things that tech needs think is pointless when in reality opting out of search indexing drops your visibility to nothing which is good for making sure your posts don’t “break containment.”

Unless you’re a public figure or social media influencer having a post tied to your IRL identity blow up is usually a bad thing.
