When all of her friends communicate through social medias, she will feel excluded if she is the only one without it. It is the same problem as, when younger, all my friends had a phone and I hadn't. Except much worse because social media really became a big part of the social and cultural life of teenagers. I don't believe a ban would be effective unless it also applies to her social circle too. I know in some rare schools, parents organized themselves to all commit to not let their child use social medias. That might be another lead, but unlike a formal ban, it won't deter platforms to attempt to attract and retain the attention of our kids. I think in the meantime, the best approach is probably trying to limit her time using it, making her internalize the negative consequences, and try to limit the content she posts.
