Fanfic writers, please be aware this is happening. It’s probably in your best interest to make it known to your readers if you don’t want your stuff sent to these people. I know I personally wouldn’t, because they have a track record for awfulness and I don’t see them breaking the cycle any time soon. If you do find your stuff is being sent to them, I’d suggest you figure out a way to lock it up so they can’t access it.
Fanfic readers, do not under any circumstances send your favourite fics to these people without the writer’s express permission for you to do so. You don’t know what they are going to say about your favourite fic or the person who wrote it, and I’m worried this might end with a lot of people deleting their fics because of Eat Your Kimchi being terrible human beings.
