Global Spam E-mail Down After Arrests Of Botnet Owners [bbc.co.uk]
Levels of spam have fallen by almost 50% since August 2010, suggest figures.
Figures compiled by security firm Symantec show that the amount of junk e-mail messages flowing around the net has dropped 47% in three months.
Kaspersky Labs noted a similar fall from July to September, when spam levels fell to 81.1% of all e-mails
The decline was put down to the arrests of those behind spam-sending botnets, and intelligence work that saw other spamming systems shut down.
