Challenge creators wonder why the popular challenges drop drastically from thousands of entries to barely over 100. It's because it feels pointless, when those who can't afford pro perks do nothing but be downvoted after using up precious credits to create and participate.
True, as mine often are. Though sadly it's not just downvoters. I'm not the only non-pro creator who feels like "why bother", when the same months old, former-challenge-winner-pro pieces get reused to win time after time, in multiple challenges.
