I remembered, some 5-6 years ago, my ex-GF got an angry email threatening to make her naked photos public, it never happened, that's why I forgot.
Now digging up my memory, the header contained a mass mailing IP from France.
If I ever got such mail, I could care less, I'd say, go on, publish my pics, I'm proud of 'em. But girls.... it's a totally different story.
To say the least, she was stressed, imagine those fragile early 20ish females.
She never stored her pics on that PC, so yeah I agree, could be just phishing, to look at the reaction.
