I think something that could also clear this up instantly and save everyone a lot of time is David K (Skedgy Sky) coming forward and telling us what we all already know. He's been watching this thread like a hawk, and it looks like he's not going to win, so he doesn't have anything to lose.
No judgements from us, no hassle from us, no namecalling. I can understand the temptation with a prize like that. David, you could be the much bigger man between the two winning contestants right now and step forward and admit what's going on, and with how much stress and potential suffering that could save people, I don't think the community would hold it against you if you did speak up.
Does anyone else agree? He has my support if he decides to speak up, it would take guts and he has the opportunity to redeem his mistake and do a huge service for the remaining legitimate contestants
