LinkedIn have very quietly introduced some new settings that potentially seriously affect your privacy and your ability to prevent unwanted emails (spam).
These new settings are defaulted ON and include allowing LinkedIn to use profile information, names and photos in third party advertising. Please see the links below for opting out.
To reach the hard-to-reach settings options the following URL’s should take you directly to them (cut and paste into your browser if they don’t work as live links)
Manage social advertising: https://www.linkedin.com/settings/?modal=nsettings-social-advertising&tab=account
Manage enhanced advertising: https://www.linkedin.com/settings/?modal=nsettings-enhanced-advertising&tab=account
Data sharing with third party applications: https://www.linkedin.com/settings/?modal=nsettings-data-sharing&tab=groups
You may wish to consider alerting your own contacts on LinkedIn.
