I hope an amendment that would happen
or a catalyst to accelerate its progress
I doubt it. Until now the new followers came for free. The number is from start high enough that the "risk" of actually paying the prize is small.
And there's another contest on that twitter page, for the newsletter, and the winner will be picked "once we gain a good amount of new subscribers", whatever that number is.
As always in these cases, I hope I'm wrong...
