This is the new bug i discovered at orkut.
Send a message say "Happy Independence day" to all your friends. And then send a message to a few of your friends. Then go in the sent maul folder. What you will notice is that, the profile name are of your friends only, but the pictures are some other. When you click on the pictures, then you will see that, those are the pictures of some Brazilian Communities, with few members.
Donno what is this. Is orkut promoting these Brazilian Communities or there is a serious bug at orkut.
