Have you received an invitation to sign up for a social networking site called Quechup? Stay as far away from it as you can. And tell your friends to stay away from it too. Quechup claims, in its invitation, that it “will not spam or sell your email address.” Unfortunately, spam your address book is exactly what it does. Within days of accepting an invitation from a friend’s email address, Quechup launched a personalized email invitation to every single one of my gmail contacts. Every single one! You can imagine the shame and embarrassment that might cause, yet it seems to be how Quechup plans to grow its network. What kind of people could be behind such a shameful and insidious ploy? Talk about doing evil. Do me a favor and send a link to this blog post to someone you know so they will ignore Quechup just like I should have.
