What is a Spam Trap, HoneyPot, Complainer or Litigator?
“Spam traps” are usually e-mail addresses that are created not for communication, but rather to lure spam. In order to prevent legitimate email from being invited, the e-mail address will typically only be published in a location hidden from view such that an automated e-mail address harvester (used by spammers) can find the email address, but no sender would be encouraged to send messages to the email address for any legitimate purpose. Since no e-mail is solicited by the owner of this spam trap e-mail address, any e-mail messages sent to this address are immediately considered unsolicited. “ – wiki
