I think this is one of the alternatives that should be accepted in steemit. on the basis of it there are many reasons everyone uses a vote bot "steem bot tracker", because many of us are still difficult to get votes and rewards are worth it. but using it also requires good analysis, otherwise the loss will come to the user.
But that's the main question, are you willing to pay, in other words, accept a loss for promotion?
my opinion, the normative of any promotion anywhere of course, and of course applies also in steemit. But of course all back to each of them, because for users who uphold steemit idealist then they will have a different perspective, such as improving the quality of content.
