I know why YTs have been censoring themselves, and I know that the video having "Fuck" in the title is the reason. But in the past Google would just give a warning, or simply use the age listed on your account (which yes, could be faked as I did in the past). None of that is new to me.
The issue now, is that they're actually enforcing age checks, and you can't get around them without giving up personal info to Google. I am legally an adult, but now I have to show ID or use a credit card to prove it. That's the gross shit. I guess it's mostly a vent post, since this is the first time I've literally been unable to watch a video.
