parasiter: para-siter (n), a website that gathers personal information from other websites by online/electronic tracking
Nomorerack is the parasiter that tracked my online search for a specific camera before emailing me a sales link, which advertised the exact camera.

Any website whose sole purpose is to relieve its visitors of money, promising unfeasably poor services in return, although of course, you don't realise this until you've signed over your grandmother. Examples of parasites include E-Cards sites, Mobile Phone ringtone download sites (Jam**er), the various Outlook smiley plugin sites, microsoft.com.
