Is there anyone out there collating data on YouTube suggestions in a widespread way? Like a browser extension that tracks when and what videos appear vs which ones are watched. I assume doing this would be a privacy nightmare, and not capture most data 'the algorithm' runs off of. I've heard of specific studies where fresh accounts are tested and the time until certain 'radical' content starts showing up, but nothing on existing accounts in use by people. I don't have a great handle on this, since I limit the amount I use YouTube's suggestions.
