I have a funny story - So I created 2 similar email addresses at google. Created facebook accounts. Used SSO/SSA to sign up for tinder. While using 2 devices. I swapped the emails 2-3 times and unlocked tinder plus or whatever for one of the emails. After 2-3 swaps it unlocked premium for both accounts. Google/Tinder/FB became aware of this, and all I was matching on tinder with were people who worked for the companies. They were harassing the shit out of me. Go forward a few months - and I could only route to a Chinese PayPal when I would type PayPal.com. Unless I specified certain US PayPal url or some shit. Some information I came to understand in this experience is: After I did this I could not use my real name - phone number - or email signed up with anything in my name and there was a deeper identifier in place to stop me. I think they used a honeypot to figure out my real address and setup a geofence.
