Rep needs work

This site will explain everything you need to know about the rep system https://enforcement.xbox.com/en-US/home/howTo#sub-topic0-0

Here is the basic explanation for your rep

Needs Work

A user whose reputation score has continued to fall due to many reports of bad behavior. If this downward trend continues, the user will begin to be matched with only other low-reputation players.

Read the site and it will tell you what you need to know to correct it.

If someones rep drops to "needs work" or "avoid me" then it will show on their profiles on xbox live.

Other than that you can not see someones rep.

Hey dude saw the needs work on a friends profile. If Microsoft are saying your rep is perfect then double check your rep is good here enforcement.xbox.com

No, Internet Expert it is the other way around. The Enforcement page does not accurately reflect your rep and probably didn't reflect the avoid me status in the first place. The console and Xbox.com do show the real time rep. There have been quite a few
posts regarding this behavior on the Enforcement page.

If you show needs work or avoid me on your profile on the console and on Xbox.com then that is what your rep is.

Since these forums are Community forums, no one here can assist with the rep issue as most here are users like yourself OP. You will need to play more to get your rep into needs work or good player status. Xbox Support also can't help with rep but they will
send people here to get them off the phone or chat unfortunately.

a suspension or a avoid me rep?

If suspension then you must go to https://enforcement.xbox.com

If rep you must go there to figure out what reports you need to work on etc
