How come so many people are unable to spell simple words?

That's not spelling. That's grammar.
Than and Then are both spelled correctly. They are used incorrectly. The same with your and you're.

Infact the same with everything you listed. That isn't spelling, that is proper word usage.

You`re technically right, but one could argue that by using a different word they still spelt the intended word incorrectly

Should I add definitely to the OP then? That seems to be mispelt fairly often, although even then I`ve seen people use the wrong word (defiantly in this case) rather than spelling the right word correctly

Spelt or spelled look it up and you be the judge.
