It is cool that your moderators, hardly enforce that rule anymore, but shouldn't you just allow posts with comparisons between different media as long as they are within spoilers tags with appropriate titles ... a.k.a. modify that rule.
In addition, why not orginize subforums based on franchises, instead of scattering conversation to medium-based subforums? For one it will reduce the search and help focus conversation ... plus your db migration shouldn't be all that complicated. Also consider that you will avoid all the nagging about your weird choices in subforum creation. Not to mention that those image posts, however enjoyable they are, they diverge coversation, especially, when you have thread with thousands of posts, without subforums (e.g. HotD, recently).
Anyway, I hope you consider the above suggestions ;)
Finally, are you planning to offer an API to extract forum threads in an automated manner, like aniDB, MAL, vndb, etc.?
