Enourmous increase in the volume of spam e-mail sent
Companies that are low enough to resort to sending out spam e-mails as advertising have recently really been working hard. Thanks to images in spam messages, a surge in botnets (computers that are hijacked by viruses to send out spam emails), a high availability of domains for spammers and underdeveloped spam filters, spammers have managed to increase their spam volume by 35%. This exceeds the expectations of internet analysts, and means that spammed advertisements now represent 90% of all e-mails on the internet.
