That sounds like the best idea we've had so far. If they have social media pages, it shows that they are indeed real people and that they are related, and there is a very low chance of lying (like if EmpyreanSmoke were to -- hypothetically, I don't mean to say that you would do this, EmpyreanSmoke -- get two of his friends to pose as his cousins, it could fall apart fairly easily under scrutiny of pre-existing information). There will probably still be pictures involved that'll prove their existence, but ones that already exist on the Internet, so it shouldn't raise anyone's concerns about their privacy. Of course, asking them to give us links to their social media can itself be an invasion of privacy... If people want go for this option for reasonable doubt, if EmpyreanSmoke and his cousins all agree to it, and if all site users promise not to abuse the information, there shouldn't be any problem, though.
