Because Mitch212 didn't deliver on their promises to give out a prize to the winner
I didn't do research on account's background and possible links, but I had the impression the owner knows the drill and he's fishing for merits.
That's why I've decided that unlike most of the free raffles I see or participate, where I give merits to the OP because of his gesture, here I didn't; I'll wait and see how everything develops and then decide if merit is in order or not.
As Loyce said, we've seen all kinds of newbies and all kinds of raffles. It's too early to make too big of a deal of all this; we'll see in less than a week.
