In creating this dataset, you are essentially re-uploading the entire contents of Ao3 to another website.
The official Ao3 terms of service state the following: "AO3 maintains that fanworks are transformative and that a fanwork's creator owns the rights to the expressions in their work that are unique to them. A fanwork creator holds the rights to their own content, just the same as any professional author, artist, or other creator." (https://archiveofourown.org/tos_faq#fanwork_copyright).
I am not a part of the generative AI community, but I understand this project may have taken you a long time to complete. I understand you may be proud of your accomplishment. I don't know who you are. I don't know what circumstances led you to compile this data. I have no grounds on which to judge your character, nor will I try to. I only ask you take note of the legal implications of this dataset, and act accordingly.
To the people threatening violence, I understand your frustration but this is not the way to be taken seriously.
