Over the past few days, we've extended the application/added a whole manner of new things to it to hopefully do just that, and also added a notice to the rules that if we see enough of the signs that someone in-game is this person, we reserve the right to remove them.
It's the best we can do for now, I suppose.
Thank you, though. I think just hearing our "go with your gut" method doesn't make us completely horrid people helps a lot.
