This is the system that the EFF is endorsing - the Electronic Frontier Foundation, a non-profit for defending civil liberties.

For people hosting instances, however, it can also mean some legal risk. Fortunately, there are some relatively easy ways to mitigate that risk – if you plan ahead. To help people do that, this guide offers an introduction to some common legal issues, along with a few practical considerations.

Two important notes: (1) This guide is focused on legal risks that flow from hosting other people’s content, under U.S. law. In general, the safe harbors and immunities discussed below will not protect you if you are directly infringing copyright or defaming someone. (2) Many of us at EFF are lawyers, but we are not YOUR lawyers. This guide is intended to offer a high-level overview of U.S. law and should not be taken as legal advice specific to your particular situation.

…

The safe harbor doesn’t apply automatically. First, the safe harbor is subject to two disqualifiers: (1) actual or “red flag” knowledge of specific infringement; and (2) profiting from infringing activity if you have the right and ability to control it. The standards for these categories are contested; if you are concerned about them, you may wish to consult a lawyer.

Second, a provider must take some affirmative steps to qualify: Designate a DMCA agent with the Copyright Office.

By registering a DMCA agent for your site, you get to tell people who are saying “there’s copyrighted material on your site that you are hosting” to fill out the proper forms that includes their name and address and a bunch more information that they are authorized to act on behalf of the copyright holder. If they don’t have that, then you get tell them to pound sand.

This is a much better alternative for protecting a site than talking to lawyers when you don’t have the ability to rely upon section 230 as a defense for hosting user generated content.

I am for protecting the fediverse from over zealous copyright holders and copyright trolls with every legal tool available. That also comes with following the laws that exist and trying to mitigate any danger to the staff and users.

Lemmy.world is a large instance with a big target painted on it and probably many fewer lawyers than Reddit has on retainer. As such, removing piracy and copyright infringement from a site are reasonable steps to make sure that while DDOSs can take down the site, it will be harder for lawyers to do so.
