Penny stocks and sexual enhancing drugs are found to be the most common subjects of spam messages. A report published by BitDefender on the propositions most commonly solicited by image and text spam, has found that pump-and-dump penny stocks were the most common theme during the first half of 2007. Image spam is now the medium of choice and trailing behind in second place in this category, comes spam pushing sexual enhancing drugs.

While image spam was shown to be popular for penny stock spammers, BitDefender Labs found text spam to be the preferred choice for drug-related topics. Spam messages for sexual enhancing and weight loss drugs accounted for 56 per cent of all text spam. This was followed by Spam hawking replica watches, which came in at the third place in both of BitDefender’s image and text spam lists. tech
