He was probably removed from BestChange due to inactivity. It started at Week 59 in which he only posted 3 posts for that week and no post for the succeeding week. The campaign manager may have messaged him about his lack of posting and probably warned that if he didn't make the minimum post for the following week, he can get removed from the campaign. I bet that is what happened.

Anyway, I hope YOSHIE is okay.
