On the whole it seems a very good idea to restrict posts per day however one possible side-effect of that could be to encourage some posters to create multiple accounts (including industrial scale account farming).
Now that you mention it, I understand the need for a competent manager to clamp down on burst posting but in the past I have had some situations where I was busy away from the internet in general and had quite a lot of posts to make in order to meet my quota with just a couple of days remaining. It can happen to any participant but it does show aptitude from managers if they know when/who to sanction participants and when to give the benefit of the doubt (as well as know who the regular offenders are).
Who would want to be a campaign manager these days?

for me it was about discouraging burst posting (I had cases where people just made 20 posts on the last 2 days of the week). It has had the desired effect, I recently upped it to 7 from 5.
