Ubuntu Icon used in gaming servers

[Skipnaz]

I was using a small Ubuntu icon next to my name in a game for the first time when a message came up saying "reported to server admins for a discriminatory name". I did a lot of searches in the forum before I did this and only could find how to make it and couldn't find anything in text what was allowed, copyright stuff if you will. I did a search for Ubuntu copyright and nothing. Can anyone point me in the right direction as to what is right. It also appears in my gaming stats. I don't want to raise any waves to anyone, I will remove it. In my stats I give links back to Ubuntu and other open source apps. With the server admin in the game reporting it what should I do? I read where you can create it but I'm unsure if I can use it as a small icon to the left of my gaming name in a server?
Thanks in advance
