I have, yet I don't remember seeing that feature, then again CR isn't really a game for me, It is too much a Pay2Win game for my taste. (and it is too much of a bully game.)
Here I'm guessing, but the 30 days is only for the initialy 10 people you need to start the clan?
I also guess that leaders can kick any of the 9 players that are forced to stay in the clan for those 30 days and that the leader/creator can't leave the clan for those 30 days as well.
So for better and worse you are stuck together. They can be the most annoying players in the world and no one can kick them or do anything about that. (If you want to force them to stay in the clan then it is fair enough that you can't kick them or anything for those 30 days.) Here is a question: "How will you deal with people that doesn't understand boundaries. Like the question Cilakila asked: "Why should a girl stay in a clan that ask if she is hot as some of the first things they ask her?"
I'm also guessing that the 30 days (in prison) isn't for people that joins later, so they might go if the clan isn't what they expected or were promised it to be. So your clan will be as every other clan after the 30 days from the beginning?
I use to say "Being a clan leader is really not a job for everyone. There are so many clanleaders that have no clue how to lead a clan and really blame Supercell for their lack of putting in the hours, making the right rules and living by them. Leadership is hard, it is a lot work (A really lot of work and hours of it every day.)"
