Those photos clearly aren't sexual exploitation.
Also the claim that she's 15 year old cannot be validated. Trying to validate that (by posting name, date of birth, photos of documents...) would be a very bad decision.
There is nothing there that could be considered as harassment. There is no harassment on site.
If she's getting harassed on other social media or chat service, such as Facebook, Instagram, Discord, then please complain to the maintainers of those services, because they should take that seriously.
