Sometimes the screen looks clean and the connection is still alive underneath. That's the whole point of today’s article.
A lot of people remove an old phone number from a profile, delete an app, or change a setting, and assume the problem is handled, but the number is often still sitting somewhere else.
So the app disappears, but the connection doesn’t.
I think Reddit actually teaches people to build fragile privacy.
Bigger lists. More blocking. More “hardcore.”
Then everything breaks. Here’s why I think that’s backwards:
OISD and HaGeZi are not “better vs worse.” They’re different failure tolerances.
One is built to stay stable.
One is built to cut deeper.
If you choose the wrong one for your setup, you don’t get more privacy. You get breakage, blind whitelisting, and false confidence.
I broke down how to choose the one that actually fits your network:
Good privacy isn't becoming invisible. It's reducing unnecessary exposure, limiting blast radius, and preventing one compromised account, device, or identifier from exposing the rest of your life.
Can someone find your address from your phone number?
Sometimes, yes.
Not because your phone number is a GPS coordinate, but because it's a lookup key.
The number connects to records.
The records connect to addresses.
The addresses connect to more records.
Before you change your number, map what it reveals and what still depends on it.
