Symantec reported that the local ratio of spam in email traffic declined from 75.7% to 73.4%. This decline has been tracked since September 2010 which registered a high of over 90%.
The most spammed country in the world is Saudi Arabia with a spam rate of 84.8%. Our spam rate is 73.4%. In the countries highlighted by Symantec's report, the spam rates are from 72.8% (Japan) and beyond. China was second position with a spam rate of 81.6%, overtaking Russia who has a spam rate of 81.1%.
Despite this decline, we still need to be wary of spammers who seek to exploit our herd instincts by sending large volumes of spam relating to certain "pink sheets" stocks in an attempt to "pump" the value of these stocks before "dumping" them at a profit. This is a form of market manipulation by the spammers seeking to benefit from fluctuations in the turbulent financial markets. They intend to artificially drive up the price of the stock to a point where the scammers decide to sell their shares. This usually coincides with them ending the spam campaign, which in turn reduces the interest in the stock, causing the price of the stock to plummet to its original price.
