Most bots, spam bots included, are coded in Monty Python, a computer language. This explains their broken English.
Now here’s an interesting thing: Python was developed in 1991 according to this Wikipedia article
Yet here is irrefutable evidence that the spam bots have used time travel to go back in time to create themselves. The video below was made before 1975 - some 16 years before the Monty Python computer language existed. You can see the Monty Python programmers planning their spam attack. Right at the end of this 1975 video, at exactly 3:07 they talk about Facebook -30 years before it was invented.
Create themselves? The video clip more like a comedy. How on earth would they know about Facebook?
How would they know about spam?
Maybe cos they created it
