The new spam-reporting feature has been updated so that you can now report members inside your group or raid. This will allow players who are invited to groups created for purposes of spam to report the abuse appropriately.

To report this type of spam, simply right-click on the player's name in the chat interface, and choosing the "Report Spam" option. Once you have selected this option, a dialogue box will open to confirm that you wish to report the target player, and your report will be sent once you confirm your choice.

Please make sure you're only using this reporting feature for spam. All other forms of abuse should be reported appropriately, by petitioning a Game Master.
