If you thought your inbox was looking a little less full of unsolicited invitations to improve your sex life or boost the size of your manhood lately, you are not alone.
Recent months have witnessed a precipitous decline in the amount of spam email being sent out worldwide. One leading firm estimated that while 200 billion spam emails were being sent out each day during the summer, this figure plummeted to “just” 50 billion since Christmas.
Experts have observed that one of the internet's most prolific spammers, known as Rustock, has effectively ceased activities. At its peak, Rustock was firing out 44 billion spam emails every day, accounting for half of all spam sent. This has now declined to 100 million a day.
The silence from Rustock coincides with two other spam networks, Lethic and Xarvester, also going quiet. Some analysts fear this may mean the spammers are gearing up for a new raid on the world's inboxes.
