After the tragic earthquakes in Haiti and in Chile, there were no additional natural disasters for spammers to take advantage of. Instead, spammers continued to focus on seasonal and calendar events such as the Easter holiday to deliver spam messages. With respect to spam message size, there was a marked increase in spam messages between 5kb and 10kb (a rise of over 10 percentage points), which correlates to an increase in attachment spam. Overall, spam made up 89.34 percent of all messages in March, compared to 89.99 percent in February.
