Ok heres a scenario someone likes your thread and they are a digg member. They decide to digg it, 4 mins later your digged page is on diggs upcoming page and someone decides to click it. Your forum will see that the visitor is coming from digg.com and trying to access thread X, what will happen next is your forum will use diggs API to check if the thread URL is dugg if it is it will record the DIGG url and add it to your thread. Now if a thread has a digg url then the process wont be repeated.
Hope you like it, i spent some time on it
