Engagement can't replace fact checking.
I'm voting up and down all the time, it's not that I'm starting giving downvotes now. It's part of the system to chose what content gets your + or - votes.
No, I'm sure it won't be ignored, that's how it works, excessive upvotes brings downvotes (you just saw it), excessive downvotes brings upvotes. That's part of the system.
I don't see a reason to downvote all of his posts either, and I wasn't doing that.
