Multiple pages for series created and managed with inaccurate information

I work as a producer on a show that has multiple pages on IMDb. None of these pages were created or have been managed by our team. They contain inaccurate series and episode numbers, plot summaries with grammatical errors, and incorrect cast and crew credits. These pages are mostly contributed to by one user I have been unable to get in contact with, and internally we do not have the manpower to correct the credits of 100+ episodes of our series. Is there anything that can be done aside from replacing hundreds of credits individually?
