Might I suggest you re-format it so that you post a link to a listmoz and add your likes/limits there, then simply compile all the links into one big list so no one really knows which is which aside from their own? Then instead of waiting for PMs and risking the entire thing disappearing you could see not only the most recent dare, but the progression and growth of said dare.
OP didn't have a terrible concept, it's basically that children's game 'telephone circle'... However, I realize how sporadic I am at visiting my kink sites, and I know many others are just as bad [if not 10x times worse] at replying in a timely fashion...
