Please watch the categories you are adding to articles. The "index" category is only for main categories and the main series articles. Continuing to add incorrect categories can be seen as badge editing, which can lead to further consequences. Thank you.
Please stop adding inapplicable categories to pages. The category tree has been set up to allow for easy navigation without crowding the pages with categories. So there is no need to add the index category to every page.
At this point, it actually just looks like you're badge editing -editing for the sole purpose of gaining some badges- which is a blockable offense on this wiki. I advise you to be more careful with you next edits.
