I mean only in the aggregate, only if you got a big community to do it or got picked up and amplified by a political leader. I can't think of any anonymous blog posts which changed the world. Movements like Anonymous have had an impact, but there's a more to that than online screeds. The closest analog might be Q, aka an anon like Ron Watkins, but that itself was swept up in a larger movement that pushed and pulled in all sorts of different directions.

To me the idea of kids posting on Internet forums and becoming major political leaders through their pseudonyms, through logical language like a modern-day version of the Federalist Papers, does seem pretty silly in 2024.
