The thing is if you upvote your content for a penny it doesn't do much but you set the mind up to see that self-vote as good and/or okay. Once your stake becomes larger you are double dipping with your self-vote. You are making your earned votes and then taking curation rewards out of the pockets of those who vote for you. As you then become author and curator of your own post. It's all opinion but I have more respect for those who sell their vote more than anyone who steals rewards from the users upvoting them to begin with.
