This is a good question.

Well you automatically do it when you post on steemit. So I'm not sure. I know if you post on chainbb it doesn't automatically upvote when you post so it can be tested there if want or you feel like! Or I will soon and I will let you know..

Also, if you upload your post from Esteem app ,then you can upvote your article when ever you want - not automatically upvoted yourself there.
