Spam Observations #27

My pal Tony wrote to me this morning asking me the question:

has your energy level been down newly or still jaded all the time? I indubitably am, that is why i am radiant i came upon

Now this is obviously someone who has not learned their English as a first language, but this begs the question, where exactly have these annoying pests learned to write like this?

Look at those words: ‘jaded’?; ‘radiant’; ‘indubitably‘?

From Daffy Duck cartoons, perhaps? That would explain an awful lot.
