When some of us challenge them and say... If you want to down vote spam, plagiarism, or abusive behavior (doxing, trolling, etc). then you likely won't hear much complaint.
It does seem rather strange to me that the oligarch vigilantes DON'T DOWNVOTE ALL gifs and memes, which are, by any measure, both "spam" and "plagiarism" and "copyright infringement".
Some of them even use copyrighted images as avatars and homepage backgrounds.
