It seems preferable to be alienated from such a coordinated network of addicts.
They are now ~12 years old and just received their first iPhones. Parental controls/screen time is used to limit their access to social media.
I personally refuse to use TikTok. But I know that is the main App children use today. Unfortunately, I'm not sure how to handle that situation. A teenager without access to TikTok today is absolutely going to be mocked by others.

But I have no idea how young we are actually talking here, my experience with this like a decade ago (so also not quite as harmful platforms) was handling the topic at around 13 yo.
At that time though completely restricting seemed a real gamble, some of the kids with no access snuck around and were the ones behind irresponsible shit that became school gossip. For example one kid without a Facebook made an account impersonating one of his teachers, used it to friend other teachers and see their private-ish info. Got easily caught because he also friended some of his real friends with the same account and even made some timeline posts back and forth, narrowed it down real quick.
