I'm one of those people who sent their real data because I value honesty the most! I participated and used my passport on about 3-4 times because it was needed on a bounty I participated but only ended up unable to participate because the registration was closed. It was really a bad experience so I promised not to use my passport on useless KYCs anymore.
Hope I really have that excellent editing skills to fake an ID as we will never know how they are going to use our identity for the sake of money.
