Steem Frustration

I really like steem, it is an outlet for me, but when you fight so hard to gain any grounds with followers and then a bot comes along and downvotes you on stuff that is your own original material it hardly seems right or fair because then they hide your post. What is the point, if I spend a lot of time on something and then a bot is like well it is similar to something else downvote. Do these bots make money? I see why people use bots but really they should be put working hard on their steem like everyone else. Sorry had to vent
