One (more) thing to opt out of:

Freeze Your Data - The Work Number

As I understand it, payroll whores your salary out to Equifax*, who then pimps it to others

Freeze Your Data | The Work Number

You can control access to your data by requesting a data freeze at any time, at no cost. This freeze means many verifiers will be unable to view your data from The Work Number.

I hate that I have to opt out of this stuff that I never signed up for and never would have. I filed the request to freeze, and see that it will require me uploading many more pieces of data to prove identity and address. Disgusting.

No they sell it directly: https://theworknumber.com/solutions/industries/pre-employmen...

The Work Number is in fact Equifax.

I worked for Equifax many moons ago. They had a problem with people taking jobs there that no one else wanted, solely to gain access to their systems and reset their own credit scores. And, for some reason, they couldn’t roll it back once found out. Great company.
How does that work with multiple credit agencies?
No idea, it was back in the mid to late 90’s.

I'm filling out the form there. I genuinely don't know why I would ever generate a salary key so I can let someone know how much money I made.

Also, to prevent them from sharing the information, you need to give them even more information. Disgusting that this is allowed.
