Reporting is a two-edged sword. For every ticket you create, Turbine will send you an e-mail, thanking you for using the system.
I gave Turbine my spammed up e-maill addy so it doesn't really bother me.
I found this quite ironic, report spamming in-game and get spammed by the game producer.
I would like the option of clicking on the person's name and pulling a menu that says: "sending spam tells". When this message gets more than 10 hits on a counter in 2 minutes, they can disable the spammer. Auto-magic! And please don't send me e-mail thanking me, I will do it for no kudos :)
