This is understandably vague. Other people have mentioned the US FBI, but there’s also the NCMEC and IWF. If this is a professional-looking work, you may want to engage the studio’s compliance office. There are a number of very young-looking performers that were confirmed legal adults, so it might be a false alarm.

If you found something on PornHub or similar (possibly including Facebook), they usually have a ‘Report’ link. If you claim it contains minors, they will likely handle reports to the authorities automatically.

If you are looking to discuss whether a work contains a minor, outside of an abstract like the Traci Lords videos, I would recommend against it. Get the compliance records from the studio, or report it to authorities.

It’s not a thing you discuss, it’s a thing you report. If you aren’t sure, report what you do know so they can open an investigation.

In the US, you can report child exploitation to the FBI. Outside the US, you might look to see if your country has a similar internet task force.

The specifics are not something that should be discussed publicly, out of respect to the child.

I wouldn’t feel any need to discuss something like that in public. If I felt reasonably convinced that someone was being abused, I’d probably flag the FBI. Otherwise if you insist, I’m sure there there are pr0n forums. In fact Lemmy has an NSFW instance lemmynsfw.com. Stuff from there keeps showing up on lemmy.world’s front page.

You should maybe indicate if you’re critical of this exploitation or in favor. If it’s the latter it would be easier for the mods. And if it’s the former you would lessen the inherent yuckiness people feel when reading this.
