Even if she WAS over 18 when (some) of those pics were taken ... it's Revenge Porn (released by her Ex, against her will...), which is still illegal in enough US States and countries outside of the USA... with the looming threat that it could also be deemed CSAM ... I'd not touch it with a 10-foot pole... that could land you in jail pretty easily...
Idk where you guys keep getting the "all" from.. she said āSOME of them were UA. Definitely didn't say all.
