A teacher - trying to protect my identity from so many students.?

[ninjzeus]

There are many things you can do to "hide" yourself from your students, for example you can choose to provide information about your education, job, etc. You can leave those fields blank, or you could fill them in with false information (a common one is Studied at Hogwarts School of Witchcraft and Wizardry). You can also choose to upload a general photo (like the kangaroo you mentioned). Under the privacy settings (Top right gear) you can choose who sees what type of information (from email address to pictures). You can also choose who can read your posts (I have this set to friends only). If a student manages to find you anyway, and sends a request you can select to accept them or not. If they keep requesting you after you denied their request there is a block option that can be selected at the left side when you go to the privacy settings.

Hope this is enough information.

You can also google search Facebook privacy settings to see the layout, and what options are available.
