A report published by anti-spamming firm, Clean Ventures, found out that 10 per cent of UK websites are responsible for "dangerous and malicious spamming" with the number of dangerous spam having doubled in the past year alone.
The data,published (opens in new tab) on CV's Spam Ratings website, has been collected over a period of 12 months, using a sample of 10,000 UK websites and more than 150,000 emails.
A whopping 75 per cent of emails received were either unwanted, nuisance or worse, classified as "dangerous" spam email with the latter containing either pharmaceutical or sex related content, phishing attempts or simply malware.
Worryingly, it seems that some major high street names such as Argos, Moneysupermarket, Littlewoods and Findaproperty.com have automatically opted in their own consumers so that their details can be shared with "trusted" third parties.
A Stop Spam Abuse Facebook campaign has been set up by Clean Ventures here (opens in new tab) although we're not sure that the "Name and shame your worst spam offenders and win £100 of iTunes vouchers" on Facebook is a good idea.
Nearly 400 people have backed the campaign as Andy Yates, the co-founder of Spam Ratings said that "Consumers need to think twice about the origin of spam and be cautious and alert when shopping online or signing up to websites".
