There is a free speech issue. If you downvote people simply for expressing their opinion, you are going to get press articles saying "Steemit censors people who arn't happy clappy".
I can't think of a quicker way of killing this site than that. I suppose it depends on your goals. Do you want this place to succeed? Or do you want this to be a safe place where only people who post "steemit is great" on every post are allowed on the site, to make you feel good. If it is the former, then you'd be better off simply ignoring what you don't agree with. If it is the latter - by all means flag anyone who refuses to say "steemit is great" in every post - and watch as the price of steem starts to tank as the wider world realises this is only a place for sycophants.
Am waiting breathlessly to see if you downvote this comment! :-)
Whales seem to be upvoting each other comment they post.... They are now just being greedy about penny's.... I wanted to tweet about steemit to my 100k twitter followers but I thought I'd check it out before I endorsed it... More I read and explore the more I notice something jusy don't seem to on the up and up...voting on each others comments is really low brow and kill the credibility for me...I'm upvoting your post cause ...your right
Read my post again. I think you misunderstand my point.
