I believe that if @maryfavour did not experience it, she wouldn't have put it out in a post. Well, yes I agree that not all of the posts will get higher coverage. There is no manual curator who wouldn't get tired of curating the same person's post 5 time a day, leaving him/her with just 5 more times to use his/her full power votes. Remember that not everyone has the time to sit and manually vote on contents, that is why such persons chose to use steemvoter and/or streemian.
