Steemit is a decentralized platform and you can do whatever you like
but you can apply some ethical rules.
I think there is nothing wrong in upvote your own comments on steemit
because if you spend some time to write it and the others can not upvote it you
can upvote your own comment there is nothing wrong to upvote your own comment
Guys what you thing about it ????
