Changing the language on abusive user notifications

Howdy

One of our users recently received the notification in the image below after they'd mistakenly sent 3 identical DM's to one of our other community members. 

Where do I find the text that this contains in order to amend it and remove the rather aggressive sounding reference to 'abusive'?
