If you can’t get fans the old fashion way there is always the next option, make your own fans out of cardboard. When 2 of the worst teams in Japan met for a soccer match it was anticipated there would not be a large turnout. So taking in account that the stadium might be mostly empty they decided to fill the seats with cardboard cut outs of fans. Who needs real fans when you have tons of boxes? Also who wants an empty stadium? An empty stadium is super degrading, not like a stadium full of fake people, that’s not degrading at all!
