One in six consumers has responded to a message they suspected was spam, according to a survey released on Thursday by the nonprofit Messaging Anti-Abuse Working Group. Of the consumers who responded to spam, most did so by mistake, but 12 percent were interested in buying the product offered, and six percent just "wanted to see what would happen." In addition, nearly 80 percent of respondents doubted their computer was ever at risk of becoming part of a botnet. — AM
