English only please

So I'm playing a 55 the bubble and for some reason daicathai shows up and starts yapping away in the chat box in chinese or something, he types about 5 or 6 different things finally mentioning one of the seated players by name but noone responds to him.

I doubt he's cheating in any way but should I report this? Anyone have any idea WTF he was doing? Anyone have this happen to them?

It did distract me. I finally typed something like "stfu dai or speak english" and busted out immediately after saying that if I remember correctly.
