They still sell those vote and upvote bots are still working. They dowvote only those who over use them. You can still buy votes from tipu or smartsteem and I think even other accounts that were bots before, I don't know how people are buying from them, but they do. About steem power, I meant that we shouldn't delegate it for rewards, it's the same like leasing ( selling power ). It's better to keep it and to support more creators in steem including newcomers. If we think only about to earn money we will distroy steem, we need to care about creators more ! About all the platform and its future !
