The problem isn’t low quality content, that gets filtered out mostly before it reaches the front page. The problem are people who downvote based on emotional trigger, not argument. And people ganging up. Never had a case where suddenly within a minute you get 4, 5 downvotes? Seems like an organised group.
That seems more like a conspiracy theory. I think the group of people who 1) view this website and 2) click on a thread about certain topics are a heavily conditioned (and therefore more homogenized) group; if you say something that is controversial/low quality, it is likely going to get downvoted by multiple people in that group.

Well, no, I never have, but if I did, my first reaction would be to think I struck a nerve and had a bunch of people react, not that there was a conspiracy.
