Building and publishing a chess progamm can be dangerous!

This is the first comment I have ever received about the chess programm I did!
Message received today at ec@dechico.com:
Normally I visit authorized sites only and they are supposed to be old enough.
They seem to need money.
Chess Ec players, please help them!

FINAL WARNING ec@dechico.com!

You have the last chance to save your social life - I am not kidding!!
I give you the last 72 hours to make the payment before I send
the video with your masturbation to all your friends and associates.
The last time you visited a erotic website with young Teens,
you downloaded and installed the software I developed.

My program has turned on your camera and recorded your act of
Masturbation and the video you were masturbating to.
My software also downloaded all your email contact lists
and a list of your Facebook friends.
I have both the 'Ec.mp4' with your masturbation
and a file with all your contacts on my hard drive.
You are very perverted!

If you want me to delete both files and keep your secret,
you must send me Bitcoin payment. I give you the last 72 hours.
If you don't know how to send Bitcoins, search Google.

Send 2000 USD to this Bitcoin address immediately:
393Ba4kb6SSBUcwRmaWyJcYfzkA4etJFQf
(copy and paste)

1 BTC = 3850 USD right now, so send exactly 0.522903 BTC

to the address above.
Do not try to cheat me!
As soon as you open this Email I will know you opened it.

This Bitcoin address is linked to you only,
so I will know if you sent the correct amount.
When you pay in full, I will remove both files and deactivate my software.

If you don't send the payment, I will send your masturbation video
to ALL YOUR FRIENDS AND ASSOCIATES from your contact list I acquired.

Here are the payment details again:
Send 0.522903 BTC to this Bitcoin address:

----------------------------------------

----------------------------------------
You саn visit the police but nobody will help you.
I know what I am doing.
I don't live in your country and I know how to stay anonymous.
Don't try to deceive me - I will know it immediately - my spy ware is
recording all the websites you visit and all keys you press.
If you do - I will send this ugly recording to everyone you know,
including your family.
Don't cheat me! Don't forget the shame and if you ignore this message
your life will be ruined.
I am waiting for your Bitcoin payment.

P.S. If you need more time to buy and send 0.522903 BTC,
open your notepad and write '48h plz'.
I will consider giving you another 48 hours before I release the vid,
but only when I see you are really struggling to buy bitcoin.

What they have tried to make me believe about the chess programm EC:

Some people in charge of vectors and interception-strategy's software have used a part of it.
But I don't believe it.
I think it's goosip intentend to make people believe I am a VIP.
Some people also says that I should be a project-chef earning 3000€ a month.
I don't believe it either.
