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 ?
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.
