Yep. It's like the letters-to-the-editor section of the newspaper.
I played around with Facebook several years ago for a couple of weeks. I decided it wasn't safe from a cybersecurity standpoint and gave up on it. Specifically,
I will not check the box that says I accept their privacy policy/terms of service.
They are notorious for violating their privacy policy anyway.
I do not consider them a reputable company and therefore I will not whitelist them in NoScript (which would be necessary to do anything with them).
No way in hell would I give them a cell phone number or government ID number.
I find myself worrying about some of those same issues since I went from flip phone to android. It was necessary to make Google a part of my life and I really hate it. They have TMI regarding me, where I go, what I do, etc.
Yahoo has been bugging me for years to "secure" my account by giving them my cell number.
I just laugh, and close the dialogue box. They've got too much information on me already.
