I remembered another fanfiction website, And since they've been stealing from both Wattpad and Quotev, I decided to check if they were stealing from AO3

They are, and with these descriptions, I think it's safe to assume that these are people stealing these books. At least some people on this website known as teenfic at least have the courtesy do not only state that it's not theirs, but also where it originally came from. I'm going to keep investigating, so please tell me if you've had any experience with this website stealing your books, we need as much evidence as we can that this website is stealing other peoples works and uploading them.
