In "my" chat history or the server that I applied for? Because he didn't refer to my chat history, I think he's referring to the chat overall (within the server). I explain why there's a problem with the chat and spamming on the server in my app. He also says my app seems low effert, so obviously it seems like he's referring to subjects I bring up in my app and the app itself.That is what he's referring to.
He's saying exactly that - he doesn't see anything awful in your chat.
