Spam sees sudden decline

The amount of spam emails to be sent out have seen a sudden fall, after an expected surge over the Christmas period failed to appear.

According to Mac World, spam volumes for 2010 peaked towards the end of summer before seeing month on month declines of around 30 per cent between November and December.

In addition to these declines, the number of detected zombie PCs has also fallen, but the cause is unknown.

There have been no reports of rogue ISPs or botnets being taken down, so some experts have speculated that spammers could be utilising other means, for example, November saw a ten per cent rise in spam mails sent via Twitter or Facebook status updates.
