yes and no
If Reddit and its ilk didn't exist, her pictures might still be posted on some random forum, where they would probably get told to get lost because nobody was interested. But because Reddit creates a demand and a self perpetuating need for self abasement, it's the natural place to post it and to keep doing so.
Twenty years ago this would have provoked disgust, now it's just meh. Values have therefore changed, and the sites that have consistently promoted this change have been liberal ones like Reddit.
Twenty years ago the internet was still flooded with porn, if anything there was even less control.
Anyhow, her ex clearly did this to take revenge, I doubt he would have decided not to if reddit didn't exist. This kind of thing is always going to be a problem on any site with user posted content. If she's serious about stopping this she needs to call the police on her ex and take him to court. If she's not then this is just a cashgrab.
