use the same phone number, email address or credit card and they know you are the same person, use the same wifi spot or IP address with the same behaviour and they can intimate you are the same.. Even badly written data analysis can do this and a VPN from another country and different username wont convince any system with an ounce of sense.
It's trivial to use a different name, email, and phone number. Obfuscating your payment information is a bit harder, but you can request a new credit card from your bank, use a new PayPal account or similar to hide the underlying payment method, or use a prepaid card. The WiFi hotspot cannot be identified across the Internet, only the IP and other fingerprinting information leaked by the browser can, but generally speaking IPs are not fixed and tied to an individual.
My point however was not to provide an exhaustive list of workarounds, just to point out that it is the lack of privacy and anonymity in our lives and enables such surveillance.
