People who appear in spam e-mails/advertisements
 

Do you think these people are aware they're in spam e-mail (for those who get HTML e-mails), or do you think these spammers just grab random people's pictures from the web and throw them on there?

They're just stock photos... there are 100's of stock photohouses around the world. It's not like anyone puts out casting calls for "Spam Models."

EDIT: For example here is a whole bunch of different spams with the same model in them... almost definately taken from a stock photohouse. (regards to Rob Cockerham for the research)
