If a sorting system is implemented like the one I suggested. One equal vote per IP address (and per post) up or down to sort content only, that will result in a trending fix. It will highlight only the cream of the crop as far as posts are concerned. Nobody will be able to overpower it with their stake, and upsorting or downsorting won't effect rewards.
This is my suggestion because eliminating shit posts isn't possible, but what is possible is presenting a higher quality trending with a more intelligent sorting function. This will create a valuable product, similar to how a website is valuable based on the content it shows.
For example, if the Drudge Report only linked to shitty stuff people wouldn't care to visit the Drudge Report. As far as voting rewards are concerned self vote was an option baked right into the GUI. I don't see anything wrong with it, and if there is, we can fix it at the rate limited voting level.
But bear in mind, if you limit it there, you also limit all the altruistic people from distributing that much in rewards. This way people who care about Steemd's value can work to upvote articles that have made it to trending more meritoriously. I still think it serves to keep the self serving self voters because they invest in Steem and this combined with their HODL causes the token to have value. Last thing we need right now is more selling.
