That is an excellent explanation. In most cases the traffic such abuse generates is fairly insignificant. Most of the problems I encountered were caused by people using images from my Aviation Patch site in Forums. Some of them are from Operation Desert Storm, the recent conflict seemed to generate a great deal of interest in them, some people were simply displaying them in a Forum as an example of those used in the last conflict, but the real damage was being done by those who were using them as their personal logo. Some of the Forums were quite popular and the bandwidth being stolen was significant, one other undesirable affect is that when such abuse occurs, the statistics for the site are no longer a true picture of the real success or otherwise of the abused site. Even if one disregards the theft of the images, having to pay for the resources the abuser is stealing to display what they have ripped off, really goes against the grain.
