Actually I'd be very, very surprised if this was even in the jurisdiction of the EU.
So I gather you don't have any source either then.
Google even says so: https://support.google.com/youtube/answer/10070779?hl=en
>The Audiovisual Media Services Directive (AVMSD) is an EU-wide coordination of national legislation on audiovisual media – both traditional TV broadcasts and on-demand services. Recently, AVMSD was revised to extend certain rules to video sharing platforms (VSPs).
>In line with AVMSD, you may be asked to re-verify your date of birth when watching age-restricted videos. Follow the prompts to submit an image of a valid ID or credit card.
As far as 'views', in reality the vast majority of Youtube channels also get very few views. You can advertise/promote the Peertube instance just like you would promote a Youtube channel.
Another alternative is to just have Peertube mirror your YouTube channel and link to the instance in every video.
It really depends on the type of content you produce and how your content is 'discovered' but unless you are on the winning side of the Youtube algorithm, peertube isn't that worse.
