That's the exact point of this attack. They see the massive power imbalance of one user, @ranchorelaxo, and see his upvotes as having a negative affect on the reward pool. The reward pool is for the Steemit community as a whole and therefore any one individual abusing their power is seen as a threat.
A few weeks ago, it was the community keeping Bernie in check. This time, a big chunk of them seem to be on his side. So, to answer your question, Yes there is a way....use your voice. Look into Bernie's position. Look at the behavior of the @ranchorelaxo account. Determine if you think it is innocent or suspicious OR determine if you think the posts on which he voted have a proper reward when compared to similar posts. Then act accordingly using one of the following options: your upvote, downvote, abstaining or posting your thoughts.
