I would agree with Webber. Try ‘reasoning with’ them first. If that doesn’t work, I doubt they check emails but definitely remove any cookies.
I doubt you would have to go to the IP address extreme as there are too many people on DHCP these days and this could severely limit their income if they did that.
Worst case – sign up with your wife’s name (if you are married). Most likely, get a new email address like Webber said and sign up with a different CC (if needed).
