Flagging is the new downvote, with extra power. No one can say no to you, if enough people (who knows how many, 1, 5, 20? Definitely an order of magnitude less that upvotes least) do it the system automatically hides it. And unless the mods care, the system can be abused very easily.

I’ve seen posts with 500+ upvotes that were still flagged. I think the balance and automation around flagging is completely off and too easily abused.
