I’d wager that next month this community will not be that small anymore, then it could be ramped up.
To hasten that process, a subtle information drive on r/anime and other anime-related subs about Lemmy could be done. The problem is with the login process and the slight learning curve that Lemmy comes with. Hope the devs solve it sooner and streamline it better.
You only need one account to access the entire Lemmy network. So you can still access the movies community on lemmy.ml if it does become the definitive one and considering that it’s the “main” instance right now, that shouldn’t be hard either.
I mean, I’m commenting here in lemmy.world from lemmy.ml
