Delete material / tidy up Wiki page

I need help tidying up and deleting material from a Wiki page that has been created and populated by my antagonists.

Specifically, I need a section removed and updated, and it needs to be done as soon as possible - within a week. I can identify exactly which edits should be removed or updated. If you're an experienced senior Wiki editor, I hope you'll consider taking on this project. The page is currently tagged as may have had paid edits.

Thank you.
