There's certain people who can win every tournament.
The raffle is for the people who can't.
I recommend drawing the raffle, and if you draw someone that already won, then re-draw. If you draw someone that doesn't want to accept the prize, then re-draw.
No offense to swift but he posted $50,000 or whatever the hell on the forum, he doesn't need the $10 raffle prize that's intended to encourage people who can't win tourneys to sign up for them.
