Removing monetary rewards from someone with no explanation is an act of violence particularly if they were going to use those monetary rewards to benefit others.

By flagging, we DO NOT remove any reward but avoid the potential reward from pilfering out of the reward pool. Just by looking at the figure of potential reward, it's wrong to assume one's right over that sum. Potential figure is NOT real and can change in any direction. And you have not removed any monetary reward as it was never there.

On the contrary, not removing/flagging an undeserving post/comment is violence as it is a theft due to your negligence. And the theft is of common property i.e. common reward pool. It is your moral responsibility to protect the common reward pool.
