Those are both good ideas about spoilers. For the kinkmeme in particular, whitetext would probably work for top-level prompts, and then people could collapse the child comments to avoid spoilers there. I'll add instructions on how to whitetext to the kinkmeme post and to the finalized rules.

I'll put up a mod contact post and link it from the profile! Thanks for the idea.
