Oh my, and he's one I don't downvote because we had a discussion sometime back that was more civil than the usual, so I figured he was all right. Some of his comments I've seen might be a tad over the line, but still, I avoid anything too confrontational with him.
I got a fanboi from years back who uses multiple alts to downvote me, but nothing that I can't undo quicker but he can change accounts and VPN. At one point early last year, he appeared to be targeting everyone that interacted with me as well, because their comments in discussions with me all got lowrated, and it was this was even in streams outside of Poli. I guess he stopped when he realized it had no lasting effect.
