... and, most importantly, does this list contain itself?

I want to be on the list of people who are not on this list

I think it's important to consider list lengths; the people on the list of people on short lists are going to have a lot more abnormal things happen to them, good and bad, than the people on the list of people only on long lists. I do wonder which is the longer of the two lists, though.

Like a skip list. But for ... freedom?
