What's taking so long to get my gamerpic verified?

I've been waiting three days now to get my gamerpic verified but it still hasn't been verified, all my friends can change their gamer pic but I've been waiting three days and who know how much longer i have to wait, please i just want my gamerpic...

It always says (It might take a little while for your custom picture to appear while we verify it's OK}

Oh no! That's not fun. Contact Xbox Support to see if they denied your photo.

Every gamerpic has to be verified before use on Xbox, it shouldn't take long at all.

I did change my gamepic for something whitout Nudity/Sexual Content so I don't think that I get reported, I mean I was playing minecraft in solo mode.

Usually the bans to gamerpics are not by reporting, but when you submit the gamerpic Xbox will verify those pics later. So this means that doesnt matter if you play solo or multiplayer, all custom gamerpics are verified.

Hi Erik !

It might take a little while for your custom picture to appear while we verify it’s OK.
(If it’s not, it’ll be reverted to the last gamerpic or avatar you were using.)

The times I've personally changed my gamerpic to a custom one, it has taken me around 24-48 hours before.

As mentioned above, it's due to the increase in traffic. All Gamerpics have to also be verified by staff so that would take up a lot of time. They are probably going to try and make it less so.
