A free Google Chrome plugin that lets users view the email address of other LinkedIn profiles, even if they aren't connected, is in the legal cross hairs of LinkedIn.
The free Sell Hack extension provides a "hack in" button, and while it is being defended by its creators, LinkedIn and security experts aren't overly impressed with the feature.
"LinkedIn members who downloaded Sell Hack should uninstall it immediately and contact Sell Hack requesting that their data be deleted," said Krista Canfield, LinkedIn Senior Manager of Corporate Communications, in a statement to TNW. "We advise LinkedIn members to protect themselves and to use caution before downloading any third-party extension or app. Often times, as with the Sell Hack case, extensions can upload your private LinkedIn information without your explicit consent."
Meanwhile, LinkedIn plans to send Sell Hack an immediate cease and desist notification, due to at least "several violations."
UPDATE: According to the Sell Hack Blog, the plugin no longer works with LinkedIn - and any collected information has been deleted by the company. A future update that doesn't violate the LinkedIn Terms of Service could be available later down the road.
