I think this question is much more likely to be phrased

"WHAT JUST HAPPENED TO MY REPUTATION"

or

"WHY ARE YOU ALL FLAGGING ME"

To which I would answer.

"Being flagged by somebody whose reputation is higher than yours, can negatively affect your own reputation. If a mistake has been made or you wish to redeem yourself, you could try reaching out to the flagger before the time of your flagged posts payout.

It is possible that your post has broken one of The Unwritten Rules of Steemit."
