Reputation down

If I rack up many reports in a short period of time, will my reputation automatically go down? No, your reputation will not go down until someone from the Xbox Live Policy Enforcement Team reviews the reports. If the reports are false, they will have no
impact on your reputation. If the reports are confirmed, your reputation score

so you got caught breaking the rules .. accept and move on

You can also view the reputation lvl of your account here
enforcement.xbox.com/.../Reputation you can see when and why you were marked down

Rep will go down over time.

With unjustified reports my reputation can go down?

if you dont mind me asking, what causes the reputation to go down then?

A suspension does not affect your reputation. Reputation is down to how you play games and if you are getting reported for cheating, team killing etc and over time this will drop your reputation. Also the reputation bar isn't fully green, it usually is 2
thirds full and with "good player" as the reputation.

As to yoiur suspension, there is nothing that the forums can do, nor support. Your only point of contact is through the Enforcement site and only if your suspension is over 24 hours in length.

You should also refrain from posting duplicate threads on the same issue.
