This is the main problem that I have had with regard to signature campaigns.

My philosophy on post-checking has marginal overlap with the desired outcome of the client.

It is obvious that more posts = more clicks (generally) and the service operators would want to maximize their bang for their buck. The problem is in gathering participants with high enough post quality to satisfy my criteria, while keeping costs low. I mentioned my thoughts on the pay/post model and despite having the capability of producing a high number of posts, even with a significant percentage of the total post count encompassing ineligible (and thereby unpaid) posts, the fixed-post model may still seem more appealing to clients.

I had a brief discussion with a current signature manager and they noted that in some cases, the service providers don't want to deal with variable payments. They want to see, "I pay 0.1 a week" not "I pay 0.05 to 0.015 a week" even if the average payment on the latter end could be lower.
