I have Google Translator
up and ready when I am in a freeroll with thousands of players and I don't hesitate to copy and paste their chat in an email to the poker site
, especially after the players have been advised that it's English only.
When I use the translator, sometimes I can see that the chat is innocent, but I have caught players in collusion and reported them, along with a copy of the chat and translation.
However, one problem with the translator is that is doesn't understand slang in a foreign language. So sometimes I may only get to see a few of the words that are translated into English in their chat, but not a complete sentence.
