I have recently been warned that "the primary method of harvesting email addresses is by massive
forwards." My initial reaction was to doubt that this is the "primary method."
However, I am wondering what level of threat it poses.
It seems the only way it would work would be if either someone on the distribution list was an abuser, or somewhere along the route that the email takes there is a harvester.
I am looking for insight into this problem, as to the level of risk it poses.
