That's not possible unless he's voting for his own account or accounts with no upvotes at all, in that case if the content is decent and the author behind it isn't just farming I wouldn't be for downvoting that. The issue is he's just voting with a big account whatever is on trending at the time and a lot of those accounts are already getting there from unfair autovotes from other big accounts, if people don't like the downvotes but never mind the big autovotes they get then it's a good first learning experience that pending rewards means pending for a reason. There's many who still see downvotes the wrong way and somehow completely forget that on youtube or reddit where downvotes similarly remove some visibility and potential rewards but get loud here just cause the downvotes are public and can be tracked who's casting them but it doesn't make it right that they should be able to complain. I'm all for fair upvotes and at the same time fair downvotes so I do take the time to explain and justify them, like now, but I also respect people who don't want to justify them the same way they're not justifying their upvotes and if they're being used in a bad way it's easy to counter them as there's a lot more upvote mana than downvote one and that's up to all of us to make sure people aren't being targeted by "bad" downvotes such as personal, retaliation, etc.
