I am very angry.
Yesterday I went through every contact in my Gmail account and inserted spurious characters into each email address. I then cancelled my membership at Quechup.
This morning at around 06:00 Quechup spammed everyone in my address book using the email addresses as they were when I signed up last Tuesday.
I implore all of you in the Blogosphere to get the word out regarding the shameful behaviour of this "service"
