By that logic, how can you prove you are not a bot on Hacker News? They're also banned on HN for the same reasons as /r/changemyview, after all. https://news.ycombinator.com/item?id=33945628

This is why I dislike how the Internet has become increasingly about politics and drama and less about memes.
It's not a system that can support serious debates without immense restrictions on anonymity, and those restrictions in turn become immense privacy issues 10 years later.
People really need to understand that you're supposed to have fun on the Internet, and if you aren't having fun, why be there at all?
Most importantly, I don't like how the criticism on the situation, specially some seen here, push for abdication of either privacy or of debates. There is more than one website on the Internet! You can have a website that requires ID to post, and another website that is run by an LLM that censors all political content. Those two ideas can co-exist in the vastness of the web and people are free to choose which website to visit.
