Most of the pros have a tournament-only account they use (or a team account with all the cards) that has no friends except practice partners in case the player doesn't have a full deck in a particular region. However, I think Rdu was just inexperienced and made a stupid mistake taking a friend-full account, and it's the first time I've seen this happen in an HS competition. I think a precedent needs to be set, similar to other games, where if you receive any messages at all during a game, then you forfeit that match. I don't hold it against Rdu atm though. I'm saltier that Amaz didn't Swipe off the Doomsayer in G1. Or wrath + run TBK into it. Anything except lose all your board presence when you know the Mage depends on Alexstraza to win.
