Looking into it a bit more there are also non-monitized platforms that you don't get any credit at all for. You can stop the videos being played on them but I've no real idea which platforms they are so will leave it as is.
I'd remove the ads altogether, but there's always the chance that something will go viral and make a fortune. Its a bit like the lottery. You know, in your heart of hearts, that its unlikely but that slim chance draws you in.
