@dber's post has been the best answer I've read here, it's great that it has come from a vote buyer, as it is important to see things from that perspective. It's all very well and good saying that these services are bad for Steemit etc. But the fact remains you can get rewarded for your posts and you see others getting rewarded, why not try and join the club?
At the end of the day everyone deserves a crack of the whip, and what you would hope is that people get a bit of exposure and then the quality of their content keeps them up there and growing.
I'm glad Steemit has been your methadone, keeping you from those heroin-video games :-)
