I see what you are tying to say, but I am not convinced at the fact we need the things you mentioned. If you were to check my "past history" how can you actually tell I destroyed a clan, you can't.
About the idea of posting reasons for kicking out a member, I think that is not necessary. The leader has the right to kick out a member if he or she wants to. I don't see many leaders kicking out their members for the fun of it, they usually have a reason like inactivity, or they aren't helping the clan enough.
