It's been a long time since I got a spam call. I've literally started wondering whether I somehow fell off their databases, or just managed to block the numbers used by all popular call centers. But where did spammers get my phone number?
My top suspicion is shopping online. Buying stuff with delivery to the parcel machine requires giving the #phone number, and this means that the shopping platform, the vendor, the delivery company, and most likely some SaaS software used by the vendor got my number — and every single one of them could make some side money by selling my PII.
Then, there are medical facilities. We all know how safe our data is with them (e.g. #Facebook on their phones, and give them full access to the contacts. I've done a small experiment back in the day. I've had a pseudonymous fb account, practically unused, no personal data. One day I've added my phone number to it. Should anyone be surprised that almost immediately I've gotten suggestions to connect with people, whom I could only be linked to via the fact that they had my phone number?
There are actually two problems there. One is that they were processing my phone number without my consent. The other, more important one is that they effectively doxxed me. My "contacts" have gotten a suggestion to connect to my pseudonymous account. You can imagine how severe consequences this could have for people with serious issues.
For a long time, I've considered changing my phone number, getting off the databases. The problem is that, to say it bluntly, the only way to leaking it, is to keep it in a drawer. The moment I give my phone number to the members of my family, it goes straight to Facebook, and there's nothing I can do with it — neither by friendly request, nor by threat. Here's the modern world for you.
