Exploit in battlegrounds
By default, WoW has no facilities to automatically copy/paste things in the default UI. That's not to say that the functions don't exist, just that they're not "advertised" in any way, shape or form. This is, however, a functionality offered by a great many addons ranging from chat mods to spell alert mods to background art mods. Someone, somewhere, evidently thought it would be a great idea to be abusive with such an addon.
