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.

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.
