No man, not even close. This forum is as niche as it gets. Other than the spoiler day spike in traffic, this forum is mainly for hardcore powerscalers who don't read the manga.
But it's definitely the only One Piece fan community which doesn't make me die from cringe. I mean yeah we're all a bunch of retards, but at least our retarded posts are entertaining and can be memed.
Also, you have hidden gems like the politics thread that are just a gold mine...I doubt something like that would ever be allowed anywhere else
