Madoka☆Magica 10000 Users Bookmark (in Japanese, まどか☆マギカ10000users入り Madoka☆Magica ichiman yuuzaazu iri) is a tag where illustrations that are related to the anime series Puella Magi Madoka Magica recieves at least 10000 bookmarks, or more from the users that are looking for illustrations of this series.
Since the maximum of tags available per illustration is limited up to only 10, there are some people who might took this particular tag off and replaced it with others (when the max is reached). And this particular action might cause a lot of unwanted dramas so leaving this particular tag alone is a good idea.
