They already had posts limited to 4 per day for over a year. That doesn't stop the reward pool rape. It only hurts new people that don't know about it. You could change it to 1 post per day and it still wouldn't stop this.
They just switch to using multiple accounts and up voting each other.
So imposing LIMITS will not stop the people raping the reward pool, but it may upset and frustrate other people. If it'd actually fix it I might support reducing the post count, but it doesn't.
Oh and they could just go back to voting their own comments up to insane amounts and because comment reward pool and post reward pool that results in the same problem.
So post quantity is not a solution. We did try it for about a year (maybe more).
Damn, the problem is bitter than I thought!!! comments reward pool is also an issue...
