I tried the quiz, but I also found it to be very misplaced in some questions or are very limiting or not up to par. What can I say? It was submitted in 1998, which is to say, not too relevant in today's standards.
But in any case:
You answered "yes" to 54 of 200 questions, making you 73.0% otaku pure (27.0% otaku corrupt).
Your Weirdness Factor (AKA Uniqueness Factor) is 10%, based on a comparison of your test results with 91823 other submissions for this test.
I still have no idea on this pure or corrupt (is that how bad the addiction is or something?)
