I imagine all of them will eventually stop working though.
Some methods don't work inside the EU. The only way to bypass this is to proxy to a country outside EMEA (like Canada) and use the methods listed there.
They took my German ID's front with all content blanked that want babe, DoB, and expiration date.
Took about an hour in probably done human "review" queue to check this isn't some bot-submission/low-effort fake ID.
It's not ideal, but if you heavily blur all the info except name (which they probably know already) and birth date (what they're after), they accept it with no problem.
Does youtube-dl or one of its variants get the content or is that somehow blocked by the age check? If the former then you can skip the adverts that way too. Though it would be a bit of manual faf (open page, copy URL, wait, play video from resulting local file) compared to just streaming direct from the youtube page.
YouTube-dl doesn't without a proxy but some of the variants do.
