I've had a look at this and the vast majority of your chat does seem to be song lyrics. It looks like people find that quite disruptive, I'd imagine more so for people who don't know the songs and will perceive you are just chatting random nonsense. You got reported 75 times for this disruption which triggered a review of your chat.

Within your chat there is a lot of mention of guns and cocaine, although it does seem to be song lyrics. However, there are also some references that do not appear to be song lyrics, for example use of hate terms.

On balance I've removed the temporary mute for you, given the potential that some of your inappropriate chat is replicated lyrics, but I've also sent you some of the chat that concerned us, so you can get the full context that this mute wasn't just for 'singing Johnny Cash songs'.

Moving forwards, I'd suggest you consider whether replicating hundreds of lines of song lyrics in game is considerate to other players, and if you must do it, avoid lyrics with inappropriate content.
