What should I do? What would you do?

Okay, I love outwitters to pieces. I have been playing it for a while, and I have never encoutered this before:
I have recently beaten a 2 vs. 2 game. It was an odd game. My team just barely beat the other, (we would have died if the game went on for one more turn) I was surprised but also happy. A day later, I noticed a new message in the game. I read it. It said: screw you and the b word. I was shocked. I have no idea what to do. Do you report swearing? Is swearing allowed? I am asking for everyone's opinion, wondering what they would do in this situation, because I dont want to feel awkward if this situation comes up again.
