Perhaps an addition to your guide: Although I have not tried it myself, I hear it is quite easy to run local open-source AI models. By instructing the AI to reformulate your texts whilst adopting a certain personality, one should be able to efficiently protect against stylometry. This can even work with realtime chat.
tor is an onion proxy software, and tor-browser is a custom version of firefox which uses tor to connect to the web. Usually when people say tor they mean the tor browser but you can actually have any browser use tor (although it’s less safe). You should look into something that can control a headless browser like puppeteer and have the headless browser use the tor SOCKS interface. I don’t actually know if that’s possible, never tried that, but I think that’s where you should be looking.
what you are saying is plain wrong or not explained well. Using tor with javascript enabled you are getting the javascript anonymously, however in the process of running that javascript there is a risk of deanonymisation (for instance, that javascript code could be doing fingerprinting and other bad stuff).
dnsmasq with a blocklist, like /etc/hosts except you can use wildcards on whole domains. Then you just make your router’s default dns to point to the computer running dnsmasq. https://landchad.net/dnsmasq/
