Both upvote bots are owned by Hive account@berniesanders/@nextgencrypto and the money from every paid upvote request goes directly into his wallet. To change that, first we have to know who exactly are his biggest customers. Here's the list:

A big update:

As you can see, all customers have been informed. There are now also missing several entries. They have been removed, because they were either bots, or the users asked for a removal since they didn't want to have to do anything with this. I rerspect that.

I have also been contacted by Hive account@themarkymark who claimed the Hive account@upmyvote bot for himself. It is not another one of Hive account@berniesanders bots. The bot ended on my list, because it received a substiantial Steem Power delegation by Hive account@berniesanders via bernies Hive account@engagement account.

As soon as the delegation has been removed, Hive account@upmyvote and its remaining customers will be left alone.
