Supposing you don't provide them with any accurate information about yourself, what does it really matter? Also- if you think your info is not being tracked, sold, and monetized via any other service (online or offline) you're in for quite a shock. Are you a member of a grocery store club? Do you have health insurance? Are you on any mailing lists? Ever joined a gym? Do you have any credit cards? A cell phone? Then congratulations- your information is already being bought and sold.
So you understand where I'm coming from, I am an IT Network Engineer with a Masters degree in Information Security. I have been working and teaching in the InfoSec space for almost a decade.
