What do I do when I find potential CSAM distributors?

Alright so after a rabbit hole, I found 2 accounts that I believe are selling CSAM.

Specifically, they show their TELEGRAM username, the cheese pizza emojis and pngs. One have videos of a possibly underaged girl just showing her face, and the other explicitly says Teen (Cheese Pizza emoji).

TikTok report system is weird and I’m not exactly sure what I input to report activity of “Attempting to sell CSAM via a third party website”.

I also don’t fully trust it, as a lot of reports I try to make are just rejected.

I’ll say the tiktok usernames in the comment section, so if it’s against the rules to put usernames in posts, then the comment can taken down instead of the whole post.

Tiktok has a very big problem with this I think. I’m new to it but the fact I could find it to begin with is pretty bad, and it makes me think about influencers like that Clavicular guy, and if this is how they get ahold of what they do.
