sarcasm, sarcasm, but IMHO, it would still be worth mentioning something like this in the clarification of fair play.
Are you kidding? This is obvious cheating, just like hacking a map, which means it violates fair play. What normal person would think it's okay to do that?!
I would suggest watching your streams. And you can comment, knowing that your opponent is watching. You can also tease him somehow.
