Won’t there be a lot of confusion with so many hashtags?!! I believe it’s best to stick to a max of 2/3
#PoohRain4Yuzu as majority liked
#スケーターとつながろう given by Fujitv
and maybe a #YuzuJnats2020 tag for all yuzu related content
anything more than this will create quite a bit of confusion since I’m pretty sure people will also include #Yuzuruhanyu and #羽生結弦
