I feel it would also be beneficial if (after the next update, to avoid massive retconjuration of posts made thus far) we limited ourselves to one command and one veto per 'player'

This, I do not. Limiting one post per person already reduces clutter significantly enough, but limiting commands also reduces the reader's ability to support multiple people's ideas at once. Sure, making huge lists of commands has the potential to be problematic, but if I have two very strong opinions on what to do next, but can only "input" one, that reduces my ability to participate significantly. Perhaps a limit like 3-5 would be more reasonable. Not everyone is super hyped about reading discussion.

My logic is that, with only one veto per player, a person who has decided to cause as much chaos as possible could enter 5 commands to cause chaos, making it difficult to prevent all of them from getting through. When implementing a system, it's important to consider how players can break or abuse that system.
