Your rates are very low. If you are paying on a per post basis then then you should raise your rates significantly. .001 BTC per post for senior members is more or less standard for pay per posts and 1/3 of that will probably not cut it.
Your rates for full members and members are even worse
That is true.. rates are extreamly low.. Senior can have 0.1 or more for 100-150 posts/ month. Here 100posts=0.03/150posts=0.045 - not even half.. Other members similar..
