I've found that without the upvote element, not everyone will upvote the post, but will do everything else to enter the contest in hopes of avoiding it. I've posted a pretty hefty prize pool and three equally hard-to-predict matches/games, so I hope no one views this as spam.

I've never used the resteem element before and was trying it out. I've removed that as a requirement, though...you're right, that should be optional.
