This is an interesting idea. But flagging itself is still hard work and still carries a negative connotation. It would be preferable to correct the limitations of the current distribution and validate votes individually and automatically rather than make flagging a more desirable process.
Flagging exists because the system is imperfect. While the system will always be imperfect, fighting human nature with human nature usually leads to mass causalities rather than thriving communities.
Continue to flag as you see fit (and as you please), but we should be searching for solutions so flagging can occur less often.
