Orkut is a community service, to which one can join by invitation only. I joined several monthes ago, and invited some of my friends. I deleted from the friends list the emails of those who did not wish to join orkut.
In the past few days, several of those deleted emails got an invitation from orkut (sent as if it was sent from me) again. Deleted emails, wrong (bouncing) emails, emails of friends who have not yet responded - all those were sent again.
Orkut made me appear like a spammer. And worse - big brother is storing you.
