Thank you @trostparadox,
You did well to establish a definition for malicious downvoting.
‘Malicious downvoting’ is defined as downvoting any POB post for any reason other than [1] plagiarism or [2] behavior determined to be improper via an approved community-consensus protocol.
It may be difficult at this moment to define what is "improper" but this proposed draft is getting us all one step closer to understanding. I really believe all the community can find a consensus and I'm thankful for the transparency during this process.
