The best way to check (but too late for this specific case) this, is by simply pressing T, and pressing the UP key, till you hit the message.
Say this is what everyone sees:
Your Nick : The false message here
There are two cases here:
Sorry if the reply is confusing. I'm kind of really sleepy right now ("kind of really sleepy" proves it, I believe ).
P.S. Please, feel more than free to tell me if I'm wrong about something here.
Say this is what everyone sees:
Your Nick : The false message here
There are two cases here:
1. You get: The false message here - It was not an admin, seek help immediately. Your account is not safe. And maybe your PC isn't either.
2. You get: Your Nick : The false message here - Your nick is included in the message, therefore it was not written from your account. /msg has been used. It's an admin.
2.1. Most-likely scenario: An admin, who has been just fooling around has done this. You're safe.
2.2. Worst, and very-unlikely scenario: The server could have been hacked, and a false admin could be sending false messages, but that still wouldn't concern your account and your gamepassword. You're still safe.

P.S. Please, feel more than free to tell me if I'm wrong about something here.
