truth be told, you're just as exposed to your own identity as me and anyone else on the world wide web. majority of people use gmail as their electronic mail service and that is know to track user's information for other websites. majority of social media follow suit. in addition to other devices and applications that egregiously ask the user to be track before they could even access the app/site.
sure there are a bunch of workarounds to negate being tracked and alternative services that keep you private. but the issue is that unless you have a time machine and start off fresh, by the time you gain access to this knowledge it's already to late. you can negate it as much as possible, but you're not truly under the radar. and this even mention the government involvement for some countries.
in addition, it's improbable to stay hidden online when each post and comment can tell bit by bit about the user themselves. they don't tell the world about their private information, but the droplets from the cracks can tell a wider picture. I don't fully talk about my personal information. but I can defiantly tell you that I layout a lot of things about myself if one of the user's here track the several years of my posts. if their very willing to get something out of me. and this can apply to anyone, really.
or you can just go to the cryaotic route just purge all previous post you made on the internet yearly. as long as you don't have the similar reasons for it just like him…
