I think mr. Sanders clearly revealed himself that in comments made on post that he is aware that you criticism is accurate.

He and his bot upvote themselves and respond with gratuitous downvotes and constant abuse against any criticism. Thus engaging heavily in both behaviors that the bot is said to be meant to fight.

Hopefully you can get one or a few bigger accounts engaged in this issue. If somehow enough people with power can get engaged in this then their operation can be shut down.

Not holding my breath for it to happen but if it did it would be a victory for all of steemit.
