Extraordinary claims require extraordinary proof. I will always apply skepticism first to avoid getting hoaxed:

1. I have no idea who this pundit is, nor am I familiar with his channel. Small operations have lots of incentive to sensationalize and clickbait to draw views. This guy includes an in-video add for a gold seller as well as two in-video adds selling stock in his own channel (in ~11 min). That's a major focus on money for a guy talking about child trafficking.
2. The video has no source. He gives a name, but no means of tracking it back to where it was originally posted. I can't verify his source.
3. The translation is always something to be skeptical of. I understand enough French to trust this translation however. Aside from a few paraphrased parts, the translation captures the message. I'm open to a native speaker correcting me if I missed something, but the translation looked ok.
4. No corroborating evidence is presented. He watched a video online, then made what is effectively a reaction video with 3 in-video ads and no further investigation.

This may be legit, but I have no way of knowing it from this video. If we're going to catch these predators and get justice, we're going to need a lot more than clickbaity videos with smarmy-looking hosts to get it done.

If anyone has more information that would help substantiate this, I'd be happy to see it, but for now, I wouldn't share this with anyone I wanted to think of me as a careful thinker.
