You could join the Engagement and Curation League where you can win 1 STEEM each week straight up for not placing any self-votes for the week.

And hey, you may even win some SBI too ;)

(I almost had a clean record, until I started to follow the vote trail of a friend.. and then she voted for me, and subsequently I ended up voting for myself. I haven't cursed so loud in a while let me tell you. But from that day forward I learned to put myself as an excluded author in my vote rule perimeters on SteemRewarding lol)
