I have no problem with self upvote but ALWAYS upvoting a 1-2 word comment wether self or others and authors getting paid for it is UNFAIR to those who posts great contents/comments and get zero because they only receive 0.01 SBD reward to be rounded off to zero. And that is NOT preventing spam but is actually tolerating spam (by "rich" spammers only) and pushing away "poor" newbies who can contribute great contents.
