Question 1
I have a Facebook account. The reason I opened it was because a good friend of mine used to always tell me I "must" open an account. When she passed away I wanted to see her profile and photos on Facebook so I opened an account.
Question 2
Invasion of privacy, risk of strangers collecting information about others. Question 3
That there is a risk of invasion to people's privacy  and personal lives, yet people still upload a lot of private information to their profile.
