Hey Steve!
I don't care much for people who abuse the system. There's an account called mintdice that only upvotes their own posts. I wouldn't be surprised if the good guys catch on and start down-voting him.
This is abuse and a way to fail at HIVE.
You may see I have downvoted them a lot. That sort of thing was mentioned in the previous post. Upvoting one or two of your own posts is not so bad, but if most of your votes are for yourself it's abuse. The community gets to decide the rewards.
