Ultimately, we cannot rely on the developers to fix these sort of issues. Ned has made it pretty clear that it is up to the user base to self police. These auto-vote and bot vote programs are (to my understanding) putting their vote directly on the Steem blockchain independent of the UI. I suppose the Steem team could close that door, but I don't know if closing that off would also close off other front ends like utopian and dtube.
I'm not smart enough in the ways of the code to have any real answers here. hahaha
