What's up with so many spam messages lately?

Okay. In the last few days I received so many mails from bots.

Most they were like this one:

Hi Dear,

I am “The Unknown Spamer”, 18 years old and daughter of late Sir givin Edward, a reputable businessman who died in a hospital on 12th, october 2010.
I lost my mother when I was 4 years old.

I have all documents of my late father business and some money that is left in the bank. The total fund is Two Million Five Hundrad Thousand United States Dollars. (USD 2, 500,000.00). The money is still in the bank and l am with all the documents.

Please I need your assistance in the following ways:

1.To help me get this money out of the bank and invest it in your country.
2.To help me to come over to your country to continue with my education.
3.To stand as my business partner until I am out of school to handle any investment.

If you can help me with these three things, I am promising you 20% of the total money as
soon as you receive the money in any account of your choice. Please you can contact me with my private email for more details ( seems rather not okay to add e-mails )

Your suggestions and ideas will be highly valued.
I am waiting to hear from you.
Yours truly
“The Unknown Spamer”

Names and emails were different but I received a lot of them lately. Does anyone knows what’s up?
