Okay, so I’ve got no advice about ransom ware.
But posting that you do porn on an open forum may not be the best idea, even if you think everybody does it.
I’m not gonna get preachy but I will relate the tale of the least fortunate screenshot possibly ever. I happened on this tale of woe not long after it had already reached maximum humiliation for the guy involved.
It was, IIRC, on a chevy truck (a truck forum at least, if not chevy) forums and in a thread dedicated to a picture that one of our probes had sent back of Saturn and it’s rings backlit by the distant sun. A magnificent picture that many may recall.
One fellow downloaded the picture to use as his screen picture and was so happy with how it looked that he took a screenshot and posted it to the thread.
A few post later one sharp eyed forumite responded “Nice She-Males Video folder.” and chaos ensued.
Now, we can take comfort that Freepers aren’t the sort that will delight in the misery of others and our esteemed host would not prevent an especially unfortunate post from ever being deleted OR make it the unfortunate guy’s avatar … nope, this will slide here and good that it will …. but this cautionary tale may be of use for any other forum anyone visits.
Best of luck with the other issue.

Even though they have spoofed your email address in the email you saw, you could go to the source coding of your that particular email and find the real ip address. Then, do a WHOIS search and you could come up with the place of the sender. I’m also guess that email you received is a .jpg.
It really doesn’t do any good to report to any authority that you received this. It isn’t worth anyone’s time to press on with it.
Just ignore.
