I agree that their monetization policy is pretty vague; I wish it was clearer but they probably have to cover their bases.
As for "people that abuse moderation tools for hateful or trolling purposes": these people won't be given access to the tools. According to the site [0], you only get points and level up for actually flagging things correctly, and you get kicked out if you're abusing it. And the improved flagging tools are only available once you reach a higher level. So it would be pretty hard to abuse (especially since even after all that, there's oversight).
