I'd assume reporting a lot of threads here (that are worth reporting) would make you look a lot better if you applied to moderator. Same fashion.
For maybe a better breakdown of the system I guess Gaia would work. Normal user reporting stuff > Looks good when you apply to "Forum Assistant" (gives you ability move threads, but nothing else). Do well as a Forum Assistant > Very good path to becoming global mod > Omni Mod.
Everything is there in all these communities, it is just not publicized. I am not familiar Flipnote.
EDIT:
This isn't really in reply to you specifically, but I wanted to not doublepost.
Additionally, here are how the points get divvied up.
Earn points with YouTube Heroes - YouTube Help
Which makes it clear it's not an automatic reward. There is a review of the flag.
YouTube Heroes Program Rules - YouTube Help
Says it right there: "B. POINTS ACCRUAL.
Each YouTube Hero who is in compliance with these Rules will be able to earn points for every qualifying contribution to YouTube (such as accurately flagging inappropriate videos), that is verifiable and organic, and not gamed, improperly received or otherwise in violation of these Rules, including the YouTube Community Guidelines (each a "Qualifying Contribution"). We will determine each qualifying Contribution. "
And remember when I mentioned earlier about abusive flaggers not counting as much? Turns out I was right:
"3. Any abuse of the point system, the Program, or other violative behavior, may reduce the points accrued in your program account and/or restrict or prohibit any aspect of your participation in the Program."
Further, here's how the levels play out:
Unlock rewards with YouTube Heroes - YouTube Help
Finally, this isn't something that "just happens." You have to actively seek out and apply to the Heroes program to begin accumulating points. While that won't completely stop malicious people, it definitely mitigates a lot.
