Penalty for approving Suggested edit which is rejected with Vandalism flag

Question

Today when I was trying to review suggested edit, I saw a suggested edit like: Suggested Edit on this post CodeIgniter Custom Admin URI Routes

At first sight itself it seems as a spam to me, So I rejected the suggest by selecting Vandalism option, later when I checked the status of the suggested edit I saw it is rejected.

But there was an approval also,

There can be such similar blind Approvals in Stack Overflow system, is such approval can be reduced by giving penalty ?

My idea:

If an user approves a suggested edit and if it is rejected with flag Vandalism, the approved user should be charged by some sort of penalty (-2 of-course or reduce 20 Suggested edit per day to 19 suggested edit per day).

I don't know whether it is practicable or not, but I saw similar approvals a lot of times in Stack Overflow.

Answer 1

Unfortunately, this won't always work. Sometimes an edit is incorrectly rejected as spam/vandalism, but one reviewer approves it. One such situation recently came up here: My edit was incorrectly rejected as spam

In this case, it would be improper to punish the two users who approved the edit, since it was the three who rejected it that were at fault. I think this type of a penalty system would be too likely to produce false positives and punish the wrong people.
