SENDERS of spam emails took a "holiday" in the run-up to Christmas, it emerged yesterday.
Traffic in junk messages fell away dramatically in the final few months of the year.
Experts reckon the number of spams sent worldwide plunged from around 200 billion in August to 50 billion in December.
Three of the largest producers slashed their output over Christmas - but experts warned they may just be "regrouping".
Carl Leonard, a researcher at security firm Websense, said: "If a campaign is not getting the returns they want they can stop, regroup and try something else." Most spam is sent by networks known as botnets. One of the biggest, Rustock, was responsible for 48 per cent of all spam sent globally at its peak - but was down to only 0.5 per cent last month.
There are signs that spammers are turning to alternative methods to email for distributing messages such as Facebook and Twitter.
