The promise is "Make $1000/day by upvoting 500 posts a day." That is impossible. Just pointing out the truth. Look at the post in the VincentB tag with 500+ upvotes and less than $50. You get the idea. Go ahead and use the tag and upvote all your power. No issue. Just don't think everyone will earn $1000/day. 😎
You can do that by creating really good content and building up a base of whales who like your stuff enough to upvote you. You can also do that by buying and holding cryptocurrency with growth potential like Steem. But this is not investment advice.
