Susan,
Thank you for notifying us about this. We have taken the necessary measures regarding abusive language.
Please note that from now on, abusive language will be followed by a ban period on the game's wall as well as on the public Boss Fight chat.

Also, please note that we can only intervene when abusive language is used inside the game - profile wall or public chat. If some kind of abuse occurs only through the Facebook interface, there are several methods available to report that directly to Facebook.

Thank you and please continue to leave us your feedback regarding the World Boss fight.
