I recently signed up for a new Yahoo account to use with Flickr. I have not shared the email address with anyone or any service besides Yahoo and Flickr. However, I have already received spam emails to the account. Do spammers simply bombard every permutation possible, or did they somehow get the address? I find the former more likely; the address is a derivative of my name. I do find it offensive, however, that I do not even need to distribute my email address before I receive spam messages.
