If she copied content from your wiki, you can ask her to remove it and if neccessary. You can refer to this help page when talking to her.

For other wikis: Have you made sure that she knows that wikis can be adopted? If so, I'd say contacting Fandom Staff is justified as well. If not, it would be better to explain that to her first.
