I found this interesting and was wondering how some of the larger instances handle the issues they outline such as
Copyright/DMCA Safe Harbor CSAM Law enforcement/warrants/info inquiries
And not included (since it’s focus is on US legal issues) but I’m curious about would be other regulations such as EU user data retention
Do non-US instances have to handle DMCA requests like US instance with european users have deal GDPR requests?
Not sure. I’d guess they do if they’re in a country that has a mutual IP treaty with the US but that’s definitely a question for a lawyer.
I can imagine that even hosting your own instance that copies down the content and only federates out your comments or non copyrighted material can be tricky depending on how the fediverse works (where’s an uploaded image kept when it federated out to a server?).
Is there a copy or just a reference to the original instance?
I’d be really interested in knowing how that works
Is there a copy or just a reference to the original instance?
My understanding is that the actual full size image is held just on the source instance, but that thumbnails are cached on other instances for a time.
But looking into the official documentation there seem to be json files missing and the descriptions are not completly clear: https://join-lemmy.org/docs/contributors/05-federation.html#post
And just looking around using inspect element to see the HTML source it seems that even the thumbnail is not cached for external directly hosted on lemmy image posts. But then again I also could the the preview of a image post earlier while the full size image was not visible as the hosting lemmy instance was offline.
If 4chan (I go there regularly, so I know the degen stuff posted there) can stay around for 20 years, so can lemmy.
