The easiest solution is that @ned and @steemit should delegate 1-5M SP to few moderators to counter this kind of blatant abuses. It should be for the sake of the health of steemit. Writing 10 posts each reaping $250-$300 due to one whale (or agent) voting 10 times with $280 each time is just raping the reward pool. There are other cases of abuses like commenting "Welcome to steemit" in the "intorudceyourself" section, each comment earning $30 (due to SBD price). Here are some examples:

Another way to think is that a competitor of Steemit, bought 2M SP (e.g. @ranchorelaxo) just to kill the reputation of Steemit by abusing or showing its weakness. It is similar to 51% attack on Steemit.
