I set up a redirection and tried to change my gmail address with the new one in all the important places I could (took a couple hours; now and then I notice a new one I should change). I also still have my gmail address set up in my mail client so I can answer from gmail if I need to, but that never happened in more than a year. For everyone that actually knows me I gave them the new address when it came up.

Safe to assume Herodotus would have used a Zeus notebook.

You can mostly do it with ublock origin filters. Here are mine, though they do more.

Alternatively on firefox you can use either the "unhook" extension (https://addons.mozilla.org/en-US/firefox/addon/youtube-recom...) or "enhancer for youtube" (https://addons.mozilla.org/en-US/firefox/addon/enhancer-for-...) extension (which has an option for this).
