Yes, you would think anyone with serious down voting power would only down vote harmful content. But check out the posts below (with steemd.com URLs, although the @ symbol is breaking the links). I'm not saying everyone should agree with the content. But I do believe these posts added some value to the platform. And they certainly contain no harmful content. Yet they were down voted by someone with a LOT of weight. Pretty disappointing and discouraging, I have to say. Makes me wonder why I'm spending time I really don't have in an effort to add some value here. Although I do have a sizable stake, so of course I will continue trying. But will others continue if they experience the same thing? Which takes us back to the reason I submitted the OP to begin with.
