content: Account Deleted By User I set up a separate gmail account so I could have a special Youtube channel for music. If you don't do that, you get ridiculous "suggested for you" videos. I ONLY use that account in "incognito" windows on Windows Chrome. My suggested videos frequently on this "music only" channel look a lot like videos I just viewed in the "non-incognito" window. So, they are tracking people in incognito mode. Google isn't doing it by IP address because other machines in the house don't suggest the same videos. They might be doing it through these strange auto-bookmarks that Chrome automatically accumulates across the top of your window when you open a new tab. Those suggestions look like things I've viewed in "incognito" mode even in the "non-incognito" mode. I knew the idea of Chrome "incognito" window was kind of dodgy to begin with, but when the company that makes Chrome also break its security is too much. I'd like some confirmation from others that this is going on. Maybe it's just my setup.  Is this already known?
