I’ve done a bit more research into the legality of “lolicon” content in the US (where SDF is hosted). IANAL, however, Federal law 18 U.S. Code § 1466A states:

Obscene visual representations of the sexual abuse of children
(a) In General.—Any person who, in a circumstance described in subsection (d), knowingly produces, distributes, receives, or possesses with intent to distribute, a visual depiction of any kind, including a drawing, cartoon, sculpture, or painting, that—
    (1)
        (A) depicts a minor engaging in sexually explicit conduct; and
        (B) is obscene; or
    (2)
        (A) depicts an image that is, or appears to be, of a minor engaging in graphic bestiality, sadistic or masochistic abuse, or sexual intercourse, including genital-genital, oral-genital, anal-genital, or oral-anal, whether between persons of the same or opposite sex; and
        (B) lacks serious literary, artistic, political, or scientific value;
or attempts or conspires to do so, shall be subject to the penalties provided in section 2252A(b)(1), including the penalties provided for cases involving a prior conviction.

The Department of Justice’s Citizen’s Guide To U.S. Federal Child Exploitation And Obscenity Laws states that “lolicon” is illegal and has a lower standard than obscenity in adult pornography.

In addition, Section 1466A of Title 18, United State Code, makes it illegal for any person to knowingly produce, distribute, receive, or possess with intent to transfer or distribute visual representations, such as drawings, cartoons, or paintings that appear to depict minors engaged in sexually explicit conduct and are deemed obscene. This statute offers an alternative 2-pronged test for obscenity with a lower threshold than the Miller test. The matter involving minors can be deemed obscene if it (i) depicts an image that is, or appears to be a minor engaged in graphic bestiality, sadistic or masochistic abuse, or sexual intercourse and (ii) if the image lacks serious literary, artistic, political, or scientific value. A first time offender convicted under this statute faces fines and at least 5 years to a maximum of 20 years in prison.

The Fourth Circuit Court of Appeals has upheld a conviction under 1466A in UNITED STATES v. WHORLEY (2008).

The Lemmy instance Burggit explicitly allows “lolicon” content:

Cooking up a platform for Free Thought And Expression! (NSFW & Loli/Shota/Cub friendly!) Minimal Restrictions on Content/Speech.

Since Burggit hosts content that is illegal in SDF’s jurisdiction, I would support SDF defederating from Burggit.

I do not like defederating instances for moral/ethical reasons. If that is the mission of the instance you join, so be it. I would only defederate as a last ditch effort to stave off technical or legal problems. Burggit plays in a grey area with the legal side, but I still wouldn’t defederate until it’s demonstrably causing a problem. I would also support defederating from instances where they are abusing federation to inflict harm on other instances/users.

I just have NSFW turned off in my user settings.

I agree that it can be problematic to see some weird stuff on All, but defederating is a red button that affects everybody in the instance, and I don’t like that. I enjoy seeing new stuff, and people can use the “block” button liberally.

However it is true that Lemmy still lacks some fine grained controls for users. I am positive that they will be implemented soon, so meanwhile we are living in this very early transition period where random shit can and will appear on our All page and we need to live with it (or use block a lot)

If users could block entire instances, I think this would go a long way towards solving the problem. Personally, I’m not for defederating unless the content is illegal in the US where the SDF instance is located.

In general, defederation would be less of an issue if single signon was a thing, and the lemmy web UI allowed for having multiple signed in accounts.

I dont see it as a big deal. When i browse all im really just looking for new communities to follow, and all that mess is blurred.

I made a second account on redditnsfw for “personal reasons”, so defederation wouldnt be a problem for me. But i just dont see the issue with staying federated.

They state that loli is banned: https://lemmynsfw.com/post/29826

I’ve noticed some of these same things as well. I’ve got so many NSFW communities on my blocklist, but they keep popping up like flies, and I’m starting to wonder if there’s a hard limit to how many communities we can block lol
