Indeed the section would have its proper uses, but there's always the issue with the misuse of such a board.
As Flo suggested, FH is geared more for a younger audience, while we do have older users, the section wouldn't be a fitting choice. It might attract the wrong uses while intended for the right use(mature discussion, more mature topics etc.). There's also the workload on the staff already. Having to heavily monitor a section labeled 18+ is already more work than what they already have with events, reports, moderation etc.
As much as i'd like to see such a board for mature topics and discussion among the older part of the community, I don't feel it's appropriate for the main age group that Feral Heart in itself is aimed for.
