I see what you are saying. Some witnesses are creating, funding, managing, or operating various pay upvote services. I think the community will realize how much they are being played by those services and the majority of the community will eventually turn on those witnesses. I see a virtual bloodbath coming when upvote service becomes a "bad name".
There is a difference between what you are doing and what those bots are doing. You have 6,096,880 Vests to vote on a witness. I'm sorry to break it to you, but that amount is nothing compared to what a witness needs to get to the top 20 where they start to make any earnings. Those upvote services are making serious bank for the owners. Compare that to the combined 528,363,062 Vests that we have as a collective to vote on the witness. That is almost 90 times the value of your vote. All the witness needs to do is get STEEM or SBD listed on a major exchange. If they won't do it for our vote, I highly doubt that they will spend any money on your vote. I think it would be different if you were a whale with over a billion vests. If you were a whale, you wouldn't worry about the money, instead you will have the witnesses doing what you tell them to do.
You still have all 30 of your witness votes. Just promise one of those votes to the witness that gets the job done and makes your STEEM more valuable. Do what you want with the other 29 votes.
