Even the ones that stay on the system march down the conveyor belt and fall off into oblivion like the candy in Lucy's chocolate factory. If your post does not get seen, upvoted and resteemed immediately after posting it will never be seen. Does not matter how carefully you crafted it, or how many cool gifs and pictures you included. People get upset about low quality posts or nudity that is sure to get attention. But if that gets the attention, upvotes and resteems you can't really blame them on taking the path of least resistance.
