Well our former initiative brought up an issue that was brought up in this thread as well to my knowledge, jinchuriki should die after extraction unless senju or performed under specialized medical attention. It's not like "Yeah, I totally got a bijuu extracted from me, I'll just walk that off."
Secondly, during the same initiative, We thought up a standard tail unlocking system, used Nathan as a lab rat and it went down pretty well, to my knowledge, quite a few were fond of the idea especially due to the fact that a standard for such does not exist and people don't want others to go, yeah, I just got the bijuu I'm gonna just defeat it in an inner battle and unlock all tails in a day.
Then there was the host having the right to not allow pirated kg that were not earned via resets. Anyone could just go and borrow stuff.
Of course, the reason for each of the above and perhaps more were very well elaborated in past threads.
Respecting damn Naruto-verse laws/logics and not getting the bijuu if you kill the host.
Making it the kage's obligation to find a new host if the current one goes inactive or take up challenges during the period of inactivity.
Now some of these have been used multiple times by hosts but were never put up in that list, I honestly believe that every single tiny rule should be in there, otherwise people can just go "Well it's not in the biuu rules." so yeah.
Given that "some" tried incredibly hard to boycott our initiative under accusations such as being idiots, power hungry, corrupt, I thought it was more than reasonable to take responsibility and actually do some stuff after succeeding in making us calling quits due to their insults and rages. But yeah, guess I thought wrong. Don't really plan on getting involved but I guessed I had to list some given that you did ask.
