Do a quick analysis of DRs/speedy deletions on images because they're logos that are marked as "own work"

We can count an image as a logo if it's in Category:Logos or its subcats or if it was deleted and its DR or deletion reason message mentions logo

Let's look at all logos uploaded within the last year, and see if the ones marked as "own work" are more likely to have gotten deleted. It might be a little tricky to tell if deleted images have the {{own}} template because templatelinks are deleted when an image is archived - probably will have to look in the wikitext
