Unfortunately this has happened, and I have always have know there was the possibility to do so. I never understood why ZOS never removed this option or added an additional confirmation to it. Maybe they will do that in a future patch.
Anyways, these are not the things i like to see when I wake up and read my mail. Cairenn has dealt with the issue, and if you have been hit by this, contact a GM to get it restored.
If there are any other questions, I am always available by mail
Happy Gaming !
