From what I read so far, your hack is substracting points from a member, if he starts posting in a specific area of the board.
If this is correct, I have to say that you can do it already with the standard i-cash. It allows you to enter the points a user will get for a post or reply. So you only need to enter a negative amount. This will cause that this amount is substracted, if a user starts a thread or reply to a thread.
Maybe it´s a good addtion, if this substraction is also based on the usergroup (eg. mods can post without needing the points, while normal members need to pay points). And addtionally to this it would be great, if the hack prevents new posts, if a member don´t have the amount of points.
