@matcha_addict @melroy It’s not possible to stop every instance of a user posting illegal content. What’s important is that you have a clear policy, and a moderation team that consistently and proactively enforces that policy.

The EFF had a handy explainer a couple of years ago on basically that subject:

https://www.eff.org/deeplinks/2022/12/user-generated-content-and-fediverse-legal-primer

Child Sexual Abuse Material (CSAM): Service providers are required to report any CSAM on their servers to the CyberTipline operated by the National Center for Missing and Exploited Children (NCMEC), a private, nonprofit organization established by the U.S. Congress, and can be criminally prosecuted for knowingly facilitating its distribution. NCMEC shares those reports with law enforcement. However, you are not required to affirmatively monitor your instance for CSAM.

By my understanding, you don’t have to setup proactive monitoring for CSAM being federated in, but if you specifically spot CSAM or it is reported to you then you are legally obligated to report it

I would not risk it if you’re at risk of getting kicked out or something, especially if your host country is stricter on that type of content. Just join one of the existing instances and subscribe to whatever Lemmy communities you want to see federated with it.

As long as you report the content and act fast if such kind of material is on your site. Also you can disable account registration, so it only you and maybe some friends you know that have an account.

Last but not least, you can also block domains in Mbin. I blocked some domains I just do not want to federate with!

And yes you can add that in the admin panel yourself.
