I recently got a request by SW to complete a Survey run by surveymonkey. When I clicked on the page the first question asked was for me to tell them my serial number.
Given all the spamming and phonie redirect links going around, I stopped there and just deleted the message. Is SW really telling you to give them your serial number to an independent party and doing it with a bulk email?
Doesn't sound like "best practices" since anyone can data mine this listserve for addresses. I get phonie bank requests all the time saying, "We need to confirm your bank number. Please tell us what it is!" Right.
