Infoworld’s “Cringely” observes, regarding the nototious Quechup:
When you sign up for the site it prompts you to share your address book so you can find out which of your 10,000 close personal friends is also trolling for dates on Quechup. But instead of presenting you with a list of friends, Quechup sends an invite from you to everyone in your book — making you look like a nasty purveyor of pork.
I’ve received several dozen of these spams, and have let the people who didn’t realize they were sending them know that they need to rethink their choices of social networks. Quechup is a great example of how to ruin social media.
