In case anyone thinks #MediaWiki is alone in not paginating all pages of results (for watchlists, in its case) — #Flickr also does it on the user's tags' pages at `https://www.flickr.com/photos/<username>/tags`.

How do I know? I'm silly and have added checksum machine tags to many of my photos. Now that page is 14 MB of HTML. But at least I can sort of find duplicates.
