The problem with simple automatic writing is that it cannot recognize context or grammar in the use of words and phrases. Poorly-done article spinning can result in unidiomatic phrasing that no human writer would choose. Some may substitute a synonym with the wrong part of speech when encountering a word that can be used as either a noun or a verb, use an obscure word that is only used within very specific contexts, or improperly substitute proper nouns. For example, "Great Britain" could be auto spun to "Good Britain". While "good" could be considered a synonym for "great", "Good Britain" does not have the same meaning as "Great Britain".

Die folgende Abbildung verdeutlicht das:
