How is the title of god nothing special? I think it would be pretty hard to get 20k+ or more without spending a lot of time or money or both.
Still, adding beyond godlike ranks is easy. We just need to come up with cool sounding rank names for 25, 30, 35 and 40k. I doubt anyone would go beyond that.
@Belial - Episodes are not a good measure. Watching a ton of naruto or bleach does not make you more of an otaku. If anything, it just limits you to a certain genre. Watching many 12 ep shows may be time better spent as an anime fan, since it exposes you to more things. Also, I don't want filler crap to be credited in any way, so titles over episodes is the way to go.
