Spam volumes show massive drop - but why?
Spam levels have dropped massively in recent months, though researchers fear this is simply because botnet operators have switched their attention to more lucrative activities.
Junk mail volumes - which reached 90 per cent last summer - are down to 75 per cent this summer, net security firm Symantec reports.
The 15 percentage points drop in spam has led to a 60 per cent decrease in total email volumes, helping reduce network congestion and server load in the process. Symantec reports that junk mail volumes that reached a high of 230 billion spam messages per day in July 2010, 90 per cent of all email traffic, are down to 39.2 billion messages per day, 72.9 per cent of all email.
