Those who aren't posting aren't getting paid, so it's fair to them and the business owner.
How is that fair towards the business owner? Yes you pay less, if people are not posting, but you miss out on the potential advertisement space, provided by people who post their full quota. {If I only post 5 times in a month, and someone are more active and they can post 50, as a business owner, looking for max value for money, would go for the person, who post their minimum 50 post, which increase my companies exposure.} Your statement makes no sense, please explain to me, why you score more from people, who post less, than their minimum?
Only way that can be true, is if the income generated from this campaign, is less than the budget, you are paying towards funding this campaign. {Then the reasoning would be, why do it?}
If, my observation is wrong, please correct me. {My intent was not to argue, but to point out, that members with low activity, is hurting your exposure}
If you felt offended, I would be more than willing to apologize.
This is simple - we are paying for 50 posts and it doesn't matter when exactly these post appear, so the recognition is the same no matter if they make these posts in 1 week or need 4 to do it. I've seen people who reach 50 in 1 or 2 days. It's all the same to us as the sig remains visible for the rest of the month.
Every month we have 2 or 3 people who couldn't reach 50 posts, this just a small percentage and is completely normal. Some write 100+ posts every month, while others just make it to 40 and the average remains the same.
No need to apologize
