It's still trivially easy to create an account on Facebook without using your real name.
The first LPT I taught me daughters when they started using the internet is that on the internet, you are a super hero - no one should know your real name.

I don't have children, and as a 20-something I know the struggle and seeming impossibility of avoiding FB products, but I try to avoid pouring my whole identity into them. It's rough when the social culture is rapidly shifting to "unless you put everything online you're not worth my time" or makes you one of those "privacy nuts."
Once you start connecting, you unmask yourself quite easily - many have tried creating spare accounts (even with VPNs and separate browser contexts) and have quite quickly been shown their exist friend set as "recommendations by FB".
