If you sign up for something and the terms include words like "Sign up to receive updates from us and our partners that we think you'll like," your email address is likely being collected for a shared or sold list. A subset of this method is called co-registration. This is where you sign up at a website, but that website also automatically, or nearly automatically, signs you up for other sites. They try to legitimize this by informing you of the additional subscriptions, or providing boxes to uncheck. This is a situation where it's not the subscriber’s intention to sign up for the material they will be receiving.

Market researchers usually have at least a bachelor’s degree in market research, statistics, sociology or other related field. Some researchers, particularly those with companies dedicated to market research and in larger corporations, have a master’s degree.
