Yeh, not like they can’t work it out.

(That said, they have no idea about my house number because I can’t get them to understand the building I’m in has multiple houses in it…)

It depends who you are trying to hide from. A VPN will hide your internet traffic from your ISP/phone company, but obviously not from the site you are visiting.

At best you might be one of may people connecting from the same (VPN) IP address, but they can still collect info from your browser/app etc to generate points to ID you if they want.
