Top Spam Categories

The most common type of spam detected in the first half of 2007 was related to commercial products, which made up 27% of all spam detected by sensors -- an increase from the 22% detected in the previous period. Commercial product spam usually consists of advertisements for commercial goods and services. It is frequently used to sell designer goods, such as watches, handbags and sunglasses, the profits from which can be substantial, given that the goods sold are often cheaply made counterfeits.
