Form based landing pages are the norm for public WiFi here in England. I just always give fake information. I’m not sure how many people give out their real name email and phone?
Agreed. Once or twice I gave a "real" email on the basis that I assumed they'd email me a confirmation-code, or similar. Since that has never happened I just enter "example@example.com", or similar, these days.
You'd be surprised how many people provide legitimate information when asked.
