I'm afraid the couple of writing servers I'm mostly active in are pretty niche and not public, but there are bigger ones that should be good as well. For example, I have heard good things about one called "Bookdun"[0], which is actually focused on writers helping each other to finish their books. They have sprint channels where a sprint bot helps run the sprints, but also other challenges encouraging people to get words written. I have never tried any "writing challenges" aside from sprints though; the other stuff sometimes feels a bit too distracting and gamified for my tastes, so can't speak to those.
