I can see this as one of those great ideas that goes bad quickly. I wonder if you could talk about how impt. it is to know what you are signing before you do but if you were to be honest- I am guessing that you would have to say that most of us don't read those (not that that is an excuse)... I am rambling but I think I might help them to understand that " if you sign this, you are bound to its terms" and what kinds of things might come up.
I found some examples online where people violated the terms and had their accounts disabled. I thought I might share those. But I also discovered some interesting things in the terms that the kids need to know... many adults probably should, too. But I really do think it's a part of media literacy that I shouldn't ignore. So I guess I'll rewrite the terms so they will understand.
