What is immoral about upvoting yourself, if you think that your content is good? What would be the point of even having SP if others try to guilt you into not rewarding / promoting who you choose to upvote, (yourself included)?? If people are banned from or attacked for upvoting their own content (comments and posts) then that's a signal for me to sell STEEM .
