A spamtrap is an email address that has never been associated with a real person role in a company. The spamtrap is placed on web pages in such a way that it can only be picked up by spammer web spiders. When email is received at the spamtrap address, it can only be spam, and so the email can be sent to the Razor network as definite spam.
Normally a spamtrap is hidden from view by using a tiny font, by hiding the email address behind another element of the page, by using the same color for the text and the background, or by another technique). The spammer's web spider will nevertheless detect the email address and add it to its database of valid email addresses.
Spamtraps can also be added to postings on Usenet, as long as it is made clear that the email address should not be used for real replies.
