The most careful proof-reading in the world won't help if the writer simply doesn't know that the word s/he has used is incorrect. The English language is full of homophones:
there/their; two/too/to; here/hear; air/heir etc. Spell checkers will not pick these up as errors because they are valid words, even though they may be used in the wrong context.
So, if I read: "She was going to
peddle her bicycle up the hill," I might assume she was going to sell her bicycle to someone who lived up the hill. However, it is much more likely that the author meant '
pedal', and was unaware of the two meanings.
When I validated here at the library, one of the commonest errors I noticed was the confusion between '
discreet' and '
discrete'. In almost all cases, the word should have been '
discreet' - in fact, I can't recall a single instance where '
discrete' was the required word.
Perhaps we shouldn't be too hard on authors who make these errors, but I would hope that if they see the validator has changed something, they might look up the word and learn the correct usage.
One amusing example from my teaching days was the following gem: "I don't like the school playground because it's full of
sweaty rapers." I was shocked until I realised that the girl was complaining about the littler problem, and meant "
sweety wrappers"! (candy wrappers - for our American friends.)
