I've seen many YC alum posts blatantly brigaded; that's what the flag button is for.
The interesting thing about the flag button is that it's more impactful than an upvote, which means that if the system is gamed and an article is vote-rigged, it makes the article more prone to be flagged and it immediately corrects itself. It's an unstable equilibrium.
