Given the multiple articles I've seen on how federation can easily accidentally DDOS mastodon servers, which isn't even a form of federation that primarily uses something as heavy in data usage as video, I do not find that so strange tbh. And that's before factoring in malicious actors or even just careless ones like all the AI scrapers.
It's a thing, it happens a lot and Lemmy instances have the same problems to fight. Unwanted porn in my eyeballs is sadly a not uncommon experience until you've put in effort to set up blocks and filters on your personal accounts. Peertube being explicitly video based is a natural target for porn pushers.

I'm also sceptical that activitypub is a good fit for video, IPFS could be a better solution.
It's a shame the US government killed LBRY.
