Users of video services, such as Skype, should be aware of a variety of scams that may use footage and images captured without your knowledge, to blackmail you.
In one version, the scam originates from a dating website or social network site like Facebook.
Eventually, they may ask you to join a Skype (video) call with them.
During the video call the scammer may attempt to lead you into participating in intimate, sexual activity or nudity, which can later be used to blackmail you.
Fortunately they were willing to offer customers of this device a replacement. Ignorant or unscrupulous people have this bricked camera on sale to unwitting buyers.
Scammers may use carefully prepared webcam images or footage of themselves which may initially seem flattering, but can increasingly become coercive and explicit.
They steadily increase pressure on you to participate, which they record and later threaten to distribute online.
The Logitech HD Pro Webcam C920 was the substitute product. After some back and forth I received an email from Logitech explaining the replacement process. Logitech wanted various photos from different angles showing the destruction of the camera. Some 3rd party sellers on Amazon are trying to sell it.
You can find some on e Bay too with fake reviews to dupe people.
