granted I did notice they said they will check to make sure you're a real/active Steem user, which is good. so maybe that's their thing, they want it to be top-heavy so that they can manually confirm the prize goes to a real person.
still, I think they could do a top 10 or even top 25 and it wouldn't take too much time to check.
we'll just wait and see I guess hehe, fun contest either way
