How should I have handled this?

So this afternoon I was confronted with a blatant act of collusion. The end result of the hand is irrelevant, but it was extremely annoying during the hand. I sent off an email to pokerstars to report the two. Should I have even bothered?

Here's the hand:

I think that's German for No.

It is most definitely german for no, which is why I am so irritated by it.

So if it was English it wouldn't matter? I don't get it....

He's clearly telling the other player (who is actually involved in the hand) to not call my bet. The language doesn't matter, it's the substance of the message.

If you're in the middle of a hand, you can say "call" or "fold" it doesn't matter, not very nice but I don't think it's illegal on PokerStars.

How can you possibly tell what he is meaning by saying no. I doubt pokerstars can do anything since he may be answering a question he was asked before, he may have been meaning to type on an IM and it flicked to the screen. He says something in german at the start of hte hand so he may have been saying no has a response. There are so many reasons for it that i doubt there was any collusion going on

Any other text he typed before that?

The previous chat entry means "looks completely like it" according to babel fish, but that's not even enough to nab the guy for collusion.

umm, no he isn't, any further unmentioned context aside.

He said "Nien Nien"

He's holding German Virgin
