If your hashtag is not #0000, add 1.
If your hashtag is #0000, subtract 1.
If the #0000s reach -500, they win, and reset the count. If the non-#0000s reach 500, they win, and reset the count.
If you had the hashtag #0000 before, but changed your name, then you may have to be the adding side.
I thought I noticed somebody who changed their name after they posted. So another rule: If you posted, and had the hashtag #0000, but changed your name, then you can stay to be the subtractor.
(Idk if this only applies to TFM, or all of Atelier 801 but anyway.)
