Yeah. Pretty bad.

But take note that it is "BBC" so some words like "customise" is actually spelled correctly, as that's how Britain and Canada spells it.  In the USA it has a Z instead of an S.

But there is no excuse for the rest of the sloppy writing.  Don't they have editors to look over stuff like that before it's actually released to the public?

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
