On top of that, it's absurd that someone can add my phone number to their advertising platform to get my name. Unlike email addresses, phone numbers are rather finite, and the number itself is tied to a particular geographical area (for the most part).

On a related note, Facebook makes it so difficult to unlike things, unfriend people, and opt-out of information from individual advertisers. It's obviously hostile design aimed at making it as hard as possible to reduce your advertising value to them.

What Facebook is doing might not be illegal, but I think what they are doing is more unethical than many felonies. The people in charge of these decisions are getting wealthy from them, and they are never going to face consequences for their actions, which is a real shame.

Advertisers don't get any information about you from Facebook ads unless you click on an ad and tell them it yourself.

That's why I never signed up for FB's 2FA program, and give out random fake phone numbers elsewhere, like grocery stores. I'm sure [phone] will save you 10% on your tomatoes.

Do they get your name? Still I hate it when all sites ask for phone to confirm my account and then use it to target me.

I use different e-mail for FB and everyday use, yet still there are a lot of companies that target me

This works as contact matching: they provide list of contacts and FB show to those people ads, so advertiser will not gain access to your personal data.
