How do I make the spam stop?

Members of our Lion’s Club together with club helpers are all suddenly being deluged by spam mail from Linkedin. This seems to have emanated from an error made by a Lion’s member. Although there is an option on received mail to unsubscribe it is all to no effect. How do we effectively remove it from our system?

Linkedin spam, and messages purporting to come from them have become a real nuisance lately. If you have no interest or connection to Linkedin then the simplest thing to do is create a Rule in your email program, or set your Spam filter to automatically delete any emails with the word Linkedin in the message body. You can report both real and fake Linkedin messages by forwarding all details to abuse@linkedin.com. If you are an active Linkedin member then all you can do is remain vigilant, ignore emails from members you do no know or trust, never click on any links and use your web browser to visit the Linkedin.com site to check your messages and contacts.
