"more easier"? When I grew up I was taught that the comparative/superlative form of "easy" would generally be "easier" ("more easy" would also be considered acceptable, although probably less common).
"more easier" is therefore redundant, just like the Argus proof-readers (we'll ignore the fact that the sentence doesn't even make sense).
When I read that headline it just sounded WRONG.
But perhaps I'm mistaken. Perhaps I grew up in more simpler times and the world has moved on. Maybe I even just wanted to show off my education and learning in a "my dad is more bigger than your dad" fashion.
No you are absolutely correct. It just didn't feature on my radar. Maybe I'm just used to reading much worse . . .
That said. when I was at school (in the science stream) my English teacher, so disgusted with my spelling, would write out all my foibles and then add 'Bunsen burner, test tube, litmus paper' etc at the end, to mock me. Mr Lawrence, you were a *******
