i received an email inviting me to connect on LinkedIn with this guy I used to know. I don’t have a Linkedin account so it’s asking me to set one up. The weird thing is he doesn’t know my email address so I’m a bit stumped as to how he has managed to send this invite to me. I did use that email for a Facebook account on which I was once “friends” with him. However that account has long since been deleted. So the only thing I can think of is that Linkedin asked him if he’d like to invite his Facebook contacts, and somehow that has included deleted accounts. Either that or he somehow managed to get my email himself from my old Facebook account? Can anyone who uses LinkedIn shed some light on their invite process?
