Are you referring to a specific person/user? If not I don't know what you are asking then

Of course it is. But if you check through the different wikis it was shown excluded.

Who? Who are you talking about?

The users who became staff through the whole fandom.

KittenLove1311 answered that already. If you see a specific user that would help in finding an answer

Then why were you replying if you mentioned that?

If a user is promoted to staff, the log will only be shown on CC. The user right masthead tag sometimes takes a long while to be added/removed (in the case of a demotion), especially when the right is global. You can always look at Special:UserRights to see an up-to-date list of all rights for any user. The right will take effect immediately, though.

That’s exactly what I meant.

The log shows up on the wiki on which the operation was performed, I guess they could technically grant it on another wiki and then the log entry would show up there and not on CC, but the role would be global regardless.

It's the same with user creation log - it shows on the wiki where you've created the account but your account is global to all Fandom wikis.
