If it's not embarrassing, which sites require knowing your IP address?
Your IP is available to their servers. I get ads for hot women in New Mexico. Then if the carrier rerouters my packets, switches somewhere else that I am not near.
I have issues with switching computer hardware.
My bank would freak out whenever I changed from my tower PC to my laptop for on the road. The site would ask me one of my security questions, and I would click on "I will be using this computer again." Then I could log in without fanfare, until I switched computers.
This time they keep disregarding my selection. Every time I log in.
My credit card issuer is easy, just answer the question and it's good until it changes.
Yes, thinking of ditching this bank, I think they want me gone. I don't generate any fee income and I keep just enough balance to pay currently due amounts.
Or they don't like and the relationship has reached the inevitable end point.
