Sooooo Many Challenges

I am continuing to run so many challenges over on Night Cafe. I think I have about 100 different ones. I love seeing all of the different art, but man! People are petty with the voting. I have seen some beautiful art get downvoted. I heard that there is a group that join all the big challenges and upvote their friends. I personally haven't seen it, or at least I don't think I have, but a few others who run challenges have talked about it. I know of at least one host who cancelled all of their games because their work got downvoted. Seems excessive, but I get the frustration. I feel like every since NC made the changes to their credits and upped the prices, the community there became... hostile. Maybe it's just me?
