That sounds nice and simple, but it's sadly not enough. You also have to worry about other random people in your life uploading your info (even unknowingly):
I only have a test account through my company that does not even have my name and that I used only once. The suggestions they mail are eery - e.g. they suggested my girlfriend from 12 years ago which I haven't spoken to for ~6 years to that account.

I shudder to think about what info they've amassed about me even though I've never had an account.
