Pamela:Why not? Only my friends and family are going to see them.
Lorenzo:I wouldn't be so sure.
And I wouldn't post all of that personal data either or divulge personal information.
You don't know who may gain access to your page.
Pamela:There are privacy safeguards on this website.
I can block anyone I don't know from getting access, so no one can see what I post without permission.
Lorenzo:Well, the people who run the website itself have access.
They could track what you do and what you post, and extract data from your page to sell to third-party buyers.
Pamela:No, they can't do that.
I'd know if they were doing that.
Lorenzo:As I said, that's happening as we speak.
And those are the legitimate uses of your information.
Hackers can gain access, too, with malicious intent.
They can do a lot of damage with the personal data you've posted.
Pamela:So, what should I do?
Lorenzo:Take down most of your posts and photos, at least the ones you wouldn't want everyone to see.
Pamela:But that would mean no one would know anything about me.
Worse yet, it would mean having a really boring page.
Lorenzo:It's either risk being boring or risk an invasion of your privacy.
Pamela:Wow, what a dilemma!
