Just a suggestion.
You need to increase the payouts for hero and Sr members. Other campaigns are paying much more and this small amount encourages spam. Instead you can reduce the min post required, increase the min chars and of course, increase the payout per post.
I have thought of joining others many times but the advanced automated payment system of yours keeps me in.
What the hell are you talking about? How does paying this small amount encourage spam? There's no logic in that at all. Also, there is no minimum post required and this campaign obviously has it's benefits less you wouldn't still be here. Basically you're just saying "I want to get paid more".
