Josh Dun surpasses Joseph in Instagram followers. Till Dec 24, Joseph has
5,143,379 followers while Dun has 4,741,564 of them. Ever since the platform incident, Joseph's following incensement has slowed down. According to SocialBlade, Joseph gained 3,420 in last 30 days, while Josh gained 49,830 of them in the same time frame. Clearly a lot of people unfollowed Joseph either after the incident happened (during Sept 2 - Sept 8 his following declined by 9269) or whenever he posted anything on it (Dec 16 saw a 6,451 decline in following).
According to @cutmytrucee, Tyler removed "twenty one pilots" from his Instagram bio during the chaos after his tweet and added it again after the Christmas party. It's not hard to understand if you look into the band's social account - Twitter account @twentyonepilots lost 5,569 followers in the past 30 days; they already lost 6,660 followers in the week after the incident happened. Maybe Josh should be the new frontman since he's not considered a racist - you could even say that Joseph is becoming the problem of the band.
