Something strange happened the other day… I requested the "free" Community License of Syncfusion (the company that provides a lot of .net, uwp, web, etc. components).

After a few minutes they called me... although I didn't provide my phone number…
I signed up using my LinkedIn account, but there isn't my phone number there… 🤔
I don't remember I've ever shared my phone number anywhere on the internet, but ok… maybe I did in the past.

More than 800+ components for free (if you're not a big company), a really nice offer.
So I decided to send the link to my friend.

He doesn't even have LinkedIn… he created a fucking new account just for that, without any private information about himself.

10 minutes later… they called him. HOW? 😱

We checked our accounts on Syncfusion, created just before that (without writing anything about ourselves, just by clicking on "Sign In"), and they have our addresses… How do they fucking know where I live?

I still can't understand how they did it, my phone number is registered to my father, so they couldn't just search it…

The same day they sent me an email.
I answered it asking "How did you know my phone number?".
They replied: "I got your number because when you downloaded our community license you put your email and phone number.".
I never did it. They didn't ask me anything.

It'll probably remain a creepy mystery… it's really so easy for a company to steal your data, and they really do it so publicly without any problem?
