Well said.
I've stopped up-voting most self up-voted comments - I think it is fine occasionally if you want to highlight your comment but if you just do it for a regular "Great post" type comment it seems a bit much.
It is even worse if you are spamming hundreds of identical "cut and paste" comments and up-voting all of them - that is just blatant profiteering and I don't see how it can be considered any other way.
And even worse than that, the posts will all be crap too. I go to the "new" page almost every day to try and find good content but its rare. So self-voting up a crap story is going to turn our steem ocean into a sewer.
