I keep getting emails from them, telling me that someone would like to connect with me.
The names of these people are sometimes those I have emailed but not met, sometimes names I don't know but there is a tenuous connection (similar profession).
I have ignored said emails because as far as I am concerned, they are unsolicited.
Is it a scam? Or is it some Facebook-like company which uses very clever methods (i.e. phishing) of finding people you might just know?
