Hello @bonaventure24
Greetings to you hope you are doing well. Thanks for sharing your valuable content with us. Its true engagement challenge helped us a lot to be active more on steemit. Before this challenge, we just uploaded a post and left the platform and after all just checked to see the notification. Thanks steemit team for this great challenge that we come to engage in and for showing the activeness. Vote are not guaranteed but your friend didn't do job with patience so he leave the plaatform. On steemit we work hard and provide quality content with patience to achieve a higher position. Best of luck dear.
