This! And to add, the sole existence of someone having naked pictures of children is regarded as child porn, at least in the Netherlands, spreading it no matter the ways is the spreading of child porn.

I'm not sure about the laws in the country of OP, but it could be the best option to report this person to the police for possession of childporn, as that is what it technically is

If OP is in the US, might be best not to report it because some US teens have actually gotten in legal trouble for having child porn *of themselves.* The fact that OP has a video of himself jacking off means he’s in possession of child porn and could get in legal trouble.

I’d just ignore the scammer, they’re definitely not going to take the risk of distributing child porn. OP should delete any pictures or videos he has that include any underage nudity.
