I am ashamed to say I also used the upvote services on steemit and it was like a sport to get the best deals each time. A vote of 3 dollar was given every two hours for example and if you offered 50 cents and the rest was asleep you wpuld get thefull 3 dollar vote. Can you imagine that for someone earning 300 per month or less this might be a way of living. (Not me !)
