I like @therising and @gentlebot...
Not therising is buy upvote bot it also upvotes free...
Steemauoto which replaced steemvoter ,this is the best thing that has happened on steemit.you can add your friend in a fan club means whenever he posts he automatically gets an upvote from you ..you can also set % weightage of your vote...
Or you can set your curationtrail where you can get the best curation rewards ...
