I'm going to lie about my heritage on Tinder.
Why would you do that?
I want to get more matches.
I understand that you want to find more potential partners, but lying about yourself is never good a thing to do, even online. Starting off a relationship with someone on the premise of a lie is going to harm the relationship. You should just be honest and you will find someone that is interested in you!
It's Tinder what's the worst thing that could happen if they find out.
They could refuse to go on a second date. They could try to get you banned from tinder. It is better to be  honest with others than to lie and misrepresent yourself, because they will find out the truth.
