Sean and all moderators, I appreciate all of the hard work you folks are doing to make this the best photographic site on the Internet.
Getting these warnings is useful. Whilst some scams are obvious (are there people who really believe that they've been singled out to be made a multi-millionaire by a dispossessed African prince with a Hotmail address?), others are far more sophisticated traps for the unwary, and sometimes even the wary.
You folks are all late to the party. Nigerian scams didn't start with the invention of email.
In 1975, while working in the back office of an international Wall St firm, I was assigned the task of searching for the holdings of a deceased uncle of a Nigerian gentleman by the name of Onugbu C. Moulie. Onugbu never seemed to be able to come up with an account number or old statement of his uncle's, but insisted that the firm owed him money. Large waste of my time.
