I understand those who do it because they don't have time. But at least authors could be changed from time to time. Or when there is time they curate manually. But I don't understand those who goes 100% automatic. That could make more harm than good in the long term. Even the trail should be checked sometimes. They may use your stake not the way you like. It's just an opinion. Don't take it wrong. I was also autoupvoting because I didn't have time. But now I decide since it's a proof of brain I should go completely manual. Even if we give only 10 to 12 upvotes a day manual, it could be better than giving 100 automatic. Because that upvote will be big enough to be noticed, while many little ones could be so tiny. That may motivate everyone to do their best to get those big upvotes. After all, everyone is free to do with his power whatever he/she likes. Those were just my outloud ideas I shared with the community.
