I've removed most of my information from Orkut ages ago. It seems I'm getting regular mails from Orkut, exposing a rather painful flaw. As soon as someone makes you their friend, they can spam you all they want through the orkut messaging system. Someone seems to hang around in bad circles!
On that note, I recently reported (again) a phising attempt on one of those other networking systems. This time I got the following response:
> Phishing attempt: "You have won..." Thank you for your advice. We are very sorry that you were harassed by one of our members. We have removed this member from our platform.One small step for me, one lilliputter step for my mailbox!
