MS litmus tests

I was just thinking about the Mary Sue Litmus tests lately while working on archiving my OCs. (In fact, two of my characters are variantly-named "Mary Sue", though probably they're not obvious.) The popularity of litmus tests have waxed and waned over the years I've been familiar with them, and I bet at least some people argue that they're now way out of style.

Litmus tests also exist in most of my fandoms (even though some are a bit tough to find), though not in tokusatsu fandoms. I'm not sure if the fans are just not interested, that we don't have as much a problem, or just, as before, the idea/popularity of the litmus test has faded.

EDIT: Yes, my 'S' key is giving me problems, why do you ask?
