A few months ago the website SteemFollower was published by the developer and witness 
Upvote for Upvote (kind of)
Collect tokens for upvoting Steem posts within the SteemFollower ecosystem. Usually you get as many tokens as your upvote is worth. You will then receive upvotes as long as you have tokens of yourself and as long as you are upvoting at least 5 posts every day. You don't have to upvote the person who upvoted you directly, so it is technically not upvote for upvote. If you don't have your minimum daily upvotes and/or if you have no tokens your post will not be listed on SteemFollower.
Follow for Follow (kind of)
The second main feature is the follower function where you can follow up to 30 people a day and get an equal amount of followers for that over time (only if people actually do pick your account there to be followed). You can go through the list of SteemFollower users who have active follow points and follow them manually. The only way to really make up your mind about them is by checking their user name, reputation, avatar and description text. of course you can check out their actual Steemit profile but I doubt that many people do that. As long as you have follower points your own account will be listed there for others to find.
Some extra perks are the affiliate link (which I use here in the post) that every user gets to make some profit from the upvotes somebody you referred to SteemFollower makes. And then there is also an internal market where you can buy and sell your SteemFollower upvote tokens. All the above is the status quo.
New Version of SteemFollower with SMTs
Yesterday
The first big change will be the entire removal of the follower function. That of course makes the name SteemFollower a bit redundant but I guess that doesn't matter. Maybe he will change the name after all. I do think this is a very important change because the feature was in any way disturbing and put the whole platform in a bad light. Begone!
The upvote feature will stay and become the new focus point of the platform.
Instead of using internal tokens it will get its own official SMT via the new Steem system coming in early 2018. That means it will become an independent cryptocurrency with similar features like Steem and tradable against BitCoin and co.
My Ideas for the new SteemFollower
I do think that the idea in general is pretty cool. However, the way it was presented before invited people to not really read any post in the first place and just upvote anything to get the tokens and receive therefor upvotes to their own posts. Personally, I looked for people I know using the platform and upvoted their posts whenever I used SteemFollower. Either way it is not really favouring the Proof-of-Brain and rather an additional income stream.
Make it Open Source
There is no reason to not make it open source I think. The list of advantages is long: Contributions can be made by others and rewarded through 
Communities
To overcome this problem I can see the new version opening up to communities and categories. For example the 
Curation Trails
It could be merged with SteemAuto and hand out rewards for following curation trails. To avoid abusing this system it should have some form of manual approval, maybe similar to the moderator function of Utopian.io. Doing something like this would make curation trails much more interesting and many people would want to follow projects like my 
Distribute Promotion Tokens to the Upvoter
Currently you can promote your post by activating a 2x-5x feature where you pay more for each upvote according to your setting. if you do that your post will appear on the top of each list and many more people will see it. The burned tokens are either destroyed or go to SteemFollower. Instead it should give something like 90% of these extra tokens to the upvoter itself in order to make the promotion a hundred times more interesting and effective. The remaining percent could stay with the platform to cover costs.
Add Features to hide plagiarized and bad content
All users should be able to use the new SMTs to flag/hide posts which are obviously stolen or simply of super low quality. This has been one of the major problems with SteemFollower: Tons of 
A better way to find and browse posts
Currently you see 15 posts per page plus promotions. You can reload more with a click on a button. These posts are totally random. The filter options are New Posts, Top Users, Old Users, New Users and Top Inviters. None of these groups are really helpful and just give you tons of uninteresting posts from people you don't know and don't trust. Sure, it is good to spread your votes beyond your friends. But this is just not motivating at all right now. Instead there could be a Proof-of-Brain system that pushes good content further up the list. I am working on something like this myself for 1UP. I am not quite there yet to give a more concrete idea but I am sure there are many ways to accomplish this.
Conclusion
I do like the SteemFollower idea to earn tokens for upvotes. But right now it is not really valuable for the overall ecosystem of Steem because many just want to increase their earnings without caring about the content they upvote. We already have that on Steemit but here it is worth twice as much so many just do it. If the platform finds ways to make this a true curation effort than it could become a super popular and useful new website!
Hence I am really happy to hear that
