LinkedIn also uses shady-dating-site tactics. A couple of months ago I got an email from them along the lines of "We noticed you haven't logged in in awhile. You have a message waiting from someone in your extended network!". I log in, and no message - but I am presented a page prompting me to let them scrape my gmail and/or add people from a list they think I might know. I haven't used LinkedIn in a long time, and I should really attempt to delete my account.
