Dear [Author's Name],
As a concerned member of the Drabble Protection Society, I notice that your story, which has been presented as a "drabble", in fact contains more or fewer than 100 words. Its actual wordcount is [wordcount]. Since a drabble is a story of exactly 100 words, this story would be more correctly presented as a [flashfic or shortfic/nanofic].
I would like to draw your attention to the incorrect usage, and respectfully request that you correct it. This is not intended as a criticism; sadly, many people are misinformed as to the correct definition of "drabble". However, in the interest of preserving the clarity of the language, it is important that this word, which has a specific and unique definition, not be used in place of other, less precise terms.
Thank you,
[Member's name]
