Could someone see where I live by my email address?

[“El”]

Hey,
So my sister and I want to enter the same contest online but one of the rules of the contest is that "one person per household" is allowed to enter and that you have be 18 years or older.

So she entered my mom's name and her email address.

My question is if I enter my grandma's name, but still enter my email address, could someone see that we still live in the same household or can't they.

Could you please clear this up for me. Thanks.

yes, because the IP address is unique to your computer, and that is traceable very easily. solution??? use different computers

Yes through your IP.
