Sherlock Merlin Dr Who
→ Foreign Word = Misspell- I have read a lot of British fanfictions, gone to comment, only to find a million people saying "It's 'Favorite' not 'Favourite' Get a spell check." Those people bother me. In Britain, things are spelled different. Please understand this.
Exactly. I don't go round yelling at Americans for missing out the U in words like "colour" and "favourite", so what gives them the right to criticise British people for spelling those words and others with a U? Not that I'm accusing all Americans of doing this . . .
Talking of Americans, another thing that can be irritating is when they attempt to write a fanfic based on a British series, but mess up by using Americanised dialogue. For example, I once read an otherwise well-written "Doctor Who" fanfic in which the Doctor said the word "diapers". Granted he's an alien, but the show's such a British institution that it doesn't sit right when characters start using Americanisms in dialogue. Except in the case of characters like Peri (a companion from the mid-Eighties) who are clearly described as being American.
And, TheManyFacesofJester, fanfiction.net does have a list of authors who do not allow fanfiction based on their work. But I don't know if anyone has ever been caught posting stuff in defiance of that list - if they have been, the offending stories would have been deleted.
