that screenshot was his and I was able to get into the game and look like a GM as well and able to see him as a GM as well. Why else would I believe he is a GM in the first place?
He probably made you log-in into his private server. Which is totally easy to recreate.
Don't blame the game for your own selfish reasons, RO:EXE, never heard of it.
Do you realize that this is iRO? The official servers.
