On top of all this, now that i've thought about it more, Kamui and I were left waiting for an extended period of time on Isaribi to assist in Kamui's decision on our fight. So he's been inactive plenty of times as a Host.
If people like Riku have been stripped immediately on 14 days then this should be no acception, and should not be overlooked just because it has been before.
Riku gave no reason at first to why he wasn't active, and on top of that, his post was invalid while told to report, but only added more onto it. If I commented in that thread when it happened, then there was a reason why it was done in a justified way.
As for Isaribi and any other Jinchuriki who has a life with school and work, that should be plenty reason as to why it would be difficult to keep up activity. I can say I'll have a period soon where I will be required to study for something major where I work, so my activity will lessen again. There has been no leniency for Jinchuriki at a given notice should anything happen, thus we are supposed to strip right away because there was good reason why they have to choose life over RP?
This does not include those who were stripped because they gave no notice of their inactivity, just as Riku did at some point. Even I was stripped because I had major things going on in my life that I could not miss.
