If you are trying to fill up a hole, you need the D Battery

Somebody could go to jail for this. You.

The DMCA makes it a felony to circumvent protections in services. If they wanted to push this and depending on the system disabling or using some hack to bypass could be illegal.

I don’t think that anyone would actually bring the case against an individual, but a company selling any sort of device or instructions to make it easier for people could be targeted.

The government buys your data, too. And not just your government.

For any legal case, government or your spouse’s divorce attorney, it’s a low bar to soupeana “business records” from these companies.

The US needs stronger data protection and privacy laws. Unfortunately, the corporations buy enough politicians to prevent it.

When there’s a Captive Portal like the screenshot, many devices use a random but persistent mac for that network avoid reauthorization after any network drop. This will make your access to the specific network trackable.

You do realize that they are actually tracking the device itself by the hardware MAC address and other device fingerprints.

The email is just a bonus to let them legally spam you. Anti-spam laws have an exemption. If there’s a prior business relationship like shopping in their stores, they can put you on their spam list unless you opt out.

Bogus email only helps for spam but doesn’t do anything about tracking.

EDIT: For Android when there’s a Captive Portal like the screen shot. devices will use Persistent randomization which while not the hardware MAC will remain the same for the same network where they can track your visits.
