Downvoting spam and plagiarism is great. Downvoting because a post is "over-rewarded" is not. @thoughts-in-time wrote about this a month ago, as did I, where I specifically referenced a victim of this malicious downvoting, @andrianna. While she's been accused of being @elenasteem's sock puppet, not only is there no evidence for that, it was a LONG time before she had a problem with her posts getting downvoted into oblivion.

This isn't the only instance that I know of, BTW, this is simply the only one I'm aware of in which the victim isn't being particularly vocal about it. Every other victim of malicious downvoting that I know about has complained in either the Free Speech of Proof of Brain community.
