Earlier, after review, we blocked and removed several communities that were providing assistance to access copyrighted/pirated material, which is currently not allowed per Rule #1 of our Code of Conduct.
The communities that were removed due to this decision were:
We took this action to protect lemmy.world, lemmy.world's users, and lemmy.world staff as the material posted in those communities could be problematic for us, because of potential legal issues around copyrighted material and services that provide access to or assistance in obtaining it.
This decision is about liability and does not mean we are otherwise hostile to any of these communities or their users. As the Lemmyverse grows and instances get big, precautions may happen. We will keep monitoring the situation closely, and if in the future we deem it safe, we would gladly reallow these communities.
The discussions that have happened in various threads on Lemmy make it very clear that removing the communites before we announced our intent to remove them is not the level of transparency the community expects, and that as stewards of this community we need to be extremely transparent before we do this again in the future as well as make sure that we get feedback around what the planned changes are, because lemmy.world is yours as much as it is ours.
It depends on the jurisdiction. In the United States, we have the DMCA which has been weaponized by content creators and publishers, but we also have a "safe harbors" provision to the DMCA that is supposed to protect online service providers from being liable for copyright infringement based on the actions of their users - as long as they meet certain provisions and restrictions and perform certain duties and dilligence. And yet even with that in place, it does not stop content providers from suing service providers and forcing those service providers to incur the pain and expense of mounting a legal defense.
I am pretty sure that Lemmy.world admin team are European and that the instance is hosted somewhere in Europe, so they would have their own jurisdictional laws to follow.
TL/DR: even if a service provider is technically protected from the actions of their users it is still subject to provisions and conditions, and that still doesn't stop them from being sued and having to mount a defense. Some people just don't feel the hassle of all that justifies the whatever benefits they'd gain from fighting that fight.
Certainly you've heard of 'The Pirate Bay', who's 'users' famously used their platform to share copyrighted materials...the founders of The Pirate Bay were arrested, tried, and convicted, and were forced to serve jail time. Turns out the "but it was our user's doing it" defense wasn't as reliable as everyone here seems to be suggesting.
Inside the EU, they are. And when hosting is done inside the EU as well, enforcement can theoretically go as far as shutting a platform down for not complying with law enforcement, even when it is technically just 1 user that broke the law. This is especially a problem for small platforms. The big 4 usually just fight it out in court and settle a decade later with paying a 6 figure fine (peanuts to them)
