Hello! Thank you for reporting the tags for Omniscient Reader's Viewpoint. Please take the time to see how they have been processed: what tags you need to list in addition to the names e.g. gender (if known), hair color/length (if applicable), eye color (if applicable). You can see an example post in the first post of the tag admin thread.
For the Hades and Persephone tags, please add them as "Hades (Omniscient Reader's Viewpoint)" and "Persephone (Omniscient Reader's Viewpoint)", and report them in the tag admin thread afterwards.
(I'm a retired mod but still drop by from time to time to check tags. Let me know if you have any questions!)
