I was staring to receive some 30-50 mails a day with trackbacks, of course, SPAM so
I had to put an extra check, "trackback link" verification. So now is kind of a pingback.
Wikipedia
Pingback
Essentially, a Pingback is a signal (ping) sent from Site A to Site B. However, it's also a link. When Site B receives the notification signal, it automatically goes back to Site A checking for the existance of a live incoming link. If that link exists, the Pingback is recorded successfully. This makes Pingbacks less prone to SPAM than Trackbacks.
Trackback
A Trackback is simply an acknowledgment. This acknowledgment is sent via a network signal (ping) from Site A (originator) to Site B (receptor). The receptor often publishes a link back to the originator indicating its worthiness. Trackback requires both, Site A and Site B to be Trackback enabled in order to establish this communication. Trackback does not require for Site A to phisically link to Site B.
