I often see random users adding random pages to random categories, and I mostly attribute it to ignorance, rather than malice.

To deal with it, my only advice would be to follow all categories, so you get a notification email when a page is added to a category.

You can use special:Watchlist/raw to mass-add pages to your watchlist, so it's easy to copy/paste all categories from Special:AllPages.
