I've never agreed to this, but I might be on Walmart Wi-Fi from a long time ago. Once recently shopping at Walmart in person I got an email to my account saying something really creepy like, "rate your in store purchases" and sent me pictures of each item I bought IN STORE with an invitation to rate each. Also included my real name. This isn't even the email I use for my online pickup orders.

Have you tried using any email? Literal example:

[email protected]

Somw setups don't validate much

Yeah, you can pretty much assume that any random Wi-Fi asking for that information is already doing that. My local mall has one that will accept any old email but it certainly looks like this one wants you to create an actual Walmart account.

Not only were they already collecting that information, they likely are collecting information about your position in the store from wifi positioning.

Many people here suggesting a throwaway email and/or VPN. While this does migitate the impact somewhat, the only proper response is to not use their "service" and deactivate the WiFi fo your phone (else they might be tracking your MAC address).

From personal experience I've found that an OpenVPN connection routed over port 53 (same as DNS) bypasses their signin screen entirely.

Of course it's been months since I last tried since I rarely go into the store and don't have reception issues when I do. Could be they've patched it since. Still worth a shot.

Imo, this is part of the problem with lack of privacy in today's world.

People will accept this more than not, without a second thought. This leads to the taking of a little bit more until one day you are left wondering where your privacy went.

Again, this is just my humble opinion.

Have you tried using Tor? Sometimes it works.

Why can't you use cell service?

In my experience you can type any vaguely email-like string there.

[email protected]

Or something.

Well that's just plain invasive. I'll make sure to take myself off of their network next time I'm there.
