Have you looked at what content @smooth down votes? Have you looked at what content of his he up votes? I looked at his post most of which are his HBD stabililzer post, and all of them are 100% beneficiary to @hbdstabilizer , so he gets no curation from them and is basically burning hive.

When I see people mention and complain about his down votes, 90% of the time it is because rancho and haejin gave what he considers excessive rewards.

I see people commenting that he up votes his own comments, but that is pretty easy to check if a person takes the 12 seconds of time to do. (he doesn't that I noticed).

At the end of the day though when all is said and done, it is his vote and like you, me and everyone else on Hive he is allowed to vote how he feels, that includes down vote.
