I want an alternative to youtube as much as anyone, but I just don't see how peertube can be viable in a world where child abuse materials and nazi propaganda exist and can be posted there.

I mean, at least as of when I last looked at peertube, it works sort of like torrenting does, yeah? But it doesn't require you to whitelist the channels or instances you seed. Therefore: random people are going to end up seeding child abuse materials, revenge porn, hate screed videos, and so on, unknowingly and without intending to.

Lemmy already has had issues with child abuse materials because of federation and poor moderation tools. An image will get posted on one instance, then it automatically gets copied to other instances, and even if the original instances delete the image that doesn't automatically delete it off other instances. Admins have to manually contact other admins, who then each have go in and painstakingly delete it manually, and that's if all those different admins see and respond to the message. This is a problem that has been growing as lemmy gets bigger and more popular. And this is just with instance hosts - with peertube, you have individuals seeding/contributing to the hosting.

So it seems to me that peertube as it is involves a degree of moral and legal (since people can and have been deemed legally responsible for seeding torrents before) risk that is just not worth it a compared to the privacy-invading but blessedly safe option of youtube.

And even if individuals decided that risk was fine, advertisers absolutely won't, which makes the platform a no-go for channels that depend on ads rather than patreon or merch for their livelihoods.

I'll be happy if there's a reliable way around this problem that doesn't completely break the mechanism whereby peertube is supposed to work, but as of now I can't see one.
