The only proper political model to implement is a tychacracy where all decisions are governed by pure random chance. Every single post shall have the following.

20% the is removed 20% the post is untouched 20% the post is pinned. If the pin count is limited pins are organized by first in first out. 20% the user is bad for life with no chance for appeal 20% the user is made a moderator

May the odds be in your favor!
