You can complain to the police but nobody will help you.
I dont live in your country. It means nobody can trace my location even for 3 weeks.

I infected your OS.
I had access to your web-camera, when you visited porn-site.
Now I have a record of your masturbation.
We downloaded your contactlist so if you want us to stay silent I need to be paid 410 USD in bitcoins.

This is my bitcoin address 17BwFzkhaiyuZRufshbdKKkiEEpojGWET8
(something like a credit card number)

I give you 28 h after you open this letter to complete the transaction.
You can get 48 hours only write back +.

If you want us to show proofs I can send it to 5 your friends after that you will be given their links. If you want you will ask them if they have received something or not.

Goodbye. Dont forget about the disgrace.
