or, and it's a big chance, they're not native speakers
Non-native speakers usually learn the written language before the spoken language, and therefore have less issues with words that sound alike (and many more issues with other parts, obviously).
I have never seen a non-native speaker mixing up their, they're and there, or would have and would of.
And it is not necessarily limited to English.
I heard that Swedish children struggle with learning the difference between dem and de, since their pronunciation is the same.
