No It does not, especially after HF20. Do you know that if you self upvote now(since HF20) then you will not get the curator reward and the curator reward will go to reward pool and that is why it is better not to upvote self and if you really want to make some money out of your SP then you can delegate it to some bot or even you can your vote to bot.
Apart from that if you post 6/7 posts daily and self upvote then it might invite downvote from some people in the community as someone may disagree with you.
So it is better to focus on quality content creation and live in tune to the spirit of this community.
