Is it true as long as you don't say anything in chat you cannot be punished?

I've heard this several times on the forum and my friend as long as you don't say anything you won't be punished for afk or basically anything since nothing would show up on the chat logs. Has someone posted a screenshot of chatlogs without anything on them? I wanted to try it on a separate account to troll a bunch of games and see if anything happened.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
