social networking site spam scam: beware Quechup
If you get an email invite purporting to be from a friend and it turns out to be for a social networking service called "Quechup," don't even bother. Just delete it.

TechBlog warns us in Spam Alert: Just Say No to Quechup and Matt Staggs offers a comprehensive link roundup on the scam.
