Breaking purdah to offer a warning

Following a warning on Twitter I checked by spam folder and found this email from 3 weeks ago:

"Hi, dear user of gmail.com
We have installed one RAT software into you device.
For this moment your email account is hacked (see on "from address", I messaged you from your account).
Your password for ***@gmail.com: ***

I have downloaded all confidential information from your system and I got some more evidence.
The most interesting moment that I have discovered are videos records where you masturbating.

I posted my virus on porn site, and then you installed it on your operation system.
When you clicked the button Play on porn video, at that moment my trojan was downloaded to your device.
After installation, your front camera shoots video every time you masturbate, in addition, the software is synchronized with the video you choose.

For the moment, the software has collected all your contact information from social networks and email addresses.
If you need to erase all of your collected data, send me $800 in BTC (crypto currency).
This is my Bitcoin wallet: 13cyEdT7kyH2f4j9xchvDGhv1o64MYNLUS
You have 48 hours after reading this letter.

After your transaction I will erase all your data.
Otherwise, I will send video with your pranks to all your colleagues and friends!!!

And henceforth be more careful!
Please visit only secure sites!
Bye!"

Fake in any number of ways, the most obvious being that I don't have a camera on the computer. But not fake in a couple of ways. The gmail address is mine, and, more worryingly, the password is genuine too. But it isn't my gmail password. It's my password for this site, and this site only. So has the wrath had a breach? No idea. But I thought I'd call it to your attention.
