Some are abusing the use of bidbots. You will read a post, see the upvotes and the payout is really huge only to notice that all the votes are from bidbots and the funny thing, you will realize that that caliber of post is not supposed to that payout. And a minnow who has a quality content far beyond that post and will not be receiving that payout thereby discouraging him and dimming his spirit.
It's good that you have written about this, at least I know I'm not the only one who is concerned about this.
