Do you send emails at all? Except if you wrote your own program - which is certainly overkill/not worth the effort then you have a digital footprint
Even if you do write your own client, if it goes to someone else's address that bounces off a company server or ends up in a company server for the addressee to read it, it'd be stored digitally.
If you use windows 10, you are forced to have an account
No you're not forced to, you can choose to not use a Microsoft account, and just use a regular local Windows account.
When Microsoft asks you to use a Microsoft account, there's a little link near the bottom that says, "Don't have a Microsoft Account? Create a new account". Click "Create a new account", and a Create Microsoft Account form pops up. At the bottom of that second page is a link that says, "Sign in without a Microsoft Account"
Yea it's a little hidden, but as a tech-savvy user, I didn't have any difficulty finding it on Win8.1 or Win10, even the first time I encountered it, even without knowing in advance that a Microsoft Account was needed or that it could be avoided. It took me five seconds. I was like, "What? A Microsoft Account is required?! Oh, no, wait, there's a link here to skip it.". And that was the end of the matter.
This is another example of things people are freaking out about as if they are new to Win10. Win8 was the same way, three years ago. Both push but do not force the use of a Microsoft Account.
Apparently, most the internet just started freaking out and blogging about the outrage without A) reading the page B) experimenting, or C) doing a web search, and then the other half of the internet just took it at their word, without A) validating it themselves, B) doing some critical thinking, or C) doing a web search.
Someone should sell a program that "Allows you to use Win10 without a Microsoft Account!", and all it would have to do is highlight the links more clearer.
And the creepiest part of it, your labtop's webcam is being actively-secretly used to spy on YOU, even when you think its not on
Very very very very rarely does that occur. We hear about the hundreds of cases where that happens, and the potential thousands of cases where it might be happening, but not the billions of cases where it's not happening. It's a non-threat. I'm more likely to be mauled by a rampaging hippo. And if you think it is a threat, just unplug the webcam cord from your laptop's motherboard, or tape over the camera until you need it.
Most of those occurrences are from script kiddies accessing unsecured routers.
'm not even going to mention how being on LinkedIn is as important for finding a job as having diploma and work experience... and if you don't use Facebook, you must certainly be either and oddball or a terrorist.
I've purposefully avoided all social media, and have 0 searchable footprint, and it's never been an issue for me.
Social media isn't the only source of privacy invasion.
Most webpages you visit is tracked to a single device, not just by cookies, even when you don't have an account, and even when you shut your computer down and start it back up. Not paranoia, this is what we know is happening, and hundreds of companies are racing to see who can track you better and collect more data on you. There's big money in it. Most of the companies can't track you perfectly yet, but some of the biggest ones can do so almost-perfectly. Google, for example, knows every site I visit and everything I post online. Ofcourse, they just run programs over it to try to algorithmically decipher who I am - they don't have anywhere near the manpower (or the desire) to give human attention to anything I post.
Even on GameDev.net, you're being tracked by Google.
This isn't conspiracy, this is fact. The panic and drama of some people who apparently just figured this out doesn't help, but a lack of knowledge doesn't help either. This has been going on well over a decade, and isn't isolated to social media.
Some individual companies are using four or five different ways to track you, so even if one fails to pick you up, some of the others might, and then they are correlated behind the scenes.
Even apart from tracking, some companies are even developing writing-behavior-analysis tools to try and correlate articles, emails, and forum posts you've written in the past, to articles and forum posts on entirely different sites, basically "fingerprinting" your writing years after the fact, by comparing word-frequency, grammar, punctuation, spelling, idiom usage, and so on. This side of things is still being developed, and isn't being widely-deployed yet, but it'll also be invisibly ubiquitous in another four or five years.
As I said in an earlier post, we get glimpses of what's going on behind the curtains every so often, and we can connect the dots reasonably well.
If I wanted to, I could fight against it and reduce Google's knowledge of me from ~95% tracking to ~10% tracking, and also make it harder for them to correlate behind the scenes, but that's just wasted effort in my situation, even considering where I think history is going (and I don't think it's going anywhere good, believe me!). So despite me not liking where history is going, and despite me having a less optimistic view of the future than many here, I still don't think panic and exaggeration is the solution. I still use Google and I still use Win10; I'm not worried much about Microsoft, and I'm more worried about Google, but my actions up til now and moving forward is to observe, understand, contemplate, but not panic.
