Sure. kink_bingo now has a kink_wiki which gives an explanation and example of each square. Kink bingo also has a clear political purpose: a sex-positive agenda, normalizing sexualities that have been marginalized by society, and education towards this is part of the community's goal.

I suppose reading and writing "hurt-comfort" stories is in itself a "kink" in a certain sense, and therefore I support the right of these stories to exist. But the challenge still bothers me for all the above reasons.
