I don't have that many pet peeves when it comes to fanfiction, but I feel like the ones that I have are out of the ordinary. I mostly have two things that bother me in fanfiction. First off, one fanfiction pet peeve of mine is 'bashing' stories. Where the author just bashes on a particular character because they don't like them. Those really bug me, and seem completely out of character. The other, while a pet peeve, can be mildly amusing sometimes. It's when writers use terms and slang from their own country/region, even when it's not used in the area where the story that they're writing takes place. I've read so many stories that take place in America, but the writer uses terms like 'bloody' and 'torch' in ways that they just aren't used in America. Some of the writers even admit that they know that Americans say flashlight instead of torch, but they still use torch because it's what they're used to and they like it better. I've even read a story that was written by an Australian writer, and the only reason that I know they were Australian is because they used a slang term that I actually had to look up what it meant, because it's only used in Australia. Go ahead and like whatever term you like, but when you're writing a story, can we please be professional about this? Another thing that seriously bugs me, though this is just for one particular character, is when people write about Victoire Weasley and say that her nickname is Tori...yeah, no. Victoire is half French, her mother is French, her name is French. Look up how to pronounce 'Victoire' in French. It's pronounced 'Veek-twaar'...there's no way to get 'Tori' from that. Use 'Vicky' as a nickname if you must, but not Tori, please.
