Obviously that's a much bigger problem and I don't doubt it happened a ton. From the user standpoint of someone trying to just use the community, it's incredibly disheartening (especially if you have no IRL community to reach out to) to post, have a post go to 0 or negatives within minutes, and then ignored. When I still used reddit I would frequently see posts from people asking why everything was downvoted so quickly, which probably just encouraged the people who were doing it.
