I flagged a question with 4 close-votes. It looks like a fifth person came and closed the question. Under flag weight, there seemed to be no effect but the response was
none. What exactly does that mean, and under what circumstances will that show up?
It looks like you flagged the question and then cast the last close vote on it.
This is a loophole we recently "closed", so you don't get flag weight changes from that specifically.
