Rule number 1 reads loud an clear. Keep it Cozy, no biggitry.
I say federate, and anyone violating that rule can have their comment delete with a warning. If it persists, ban the user. If this becomes an overwhelming issue, defederate.
(I'm biased as I think defederation breaks lemmy into smaller, weaker, and more boring communities).
I think a number of people like to troll just a little at least, but I don't think most people make it their whole persona. I suspect we may get some trolls who would genuinely like a community about books.
Maybe I'm an optimist, but I think it's at least worth a try.
My favorite fan fiction is Dreaming of Sunshine, by Silver Queen.
But there's also
The Howling Wind
The Girl from the Whirlpool
Black Cloaks, Red Clouds
Ibiki's Apprentice
The Sun Soul
In The Box
The first five are Naruto Fanfics. If you've never watched Naruto the only one you'll have problems with is Dreaming of Sunshine, the following three diverge from Cannon quite a bit, and tell their own unique stories that completely surpass the cannon. I highly recommend them, as they read better than some books I've read. Ibiki's Apprentice is a cute one chapter short, you'll find it funny.
The Sun Soul is a pokemon fanfic that once again diverges from the cannon quite a bit, I was a big fan, but it's been a while since I've read it.
In The Box is another once chapter short, it's a Firefly fanfic, it's cute and funny. If you don't like it, I don't like you.
Beer and weed, all my writing consists of shit posts.
You've clearly put a lot of thought into this, it's gonna be awesome
Holy fuck, Gabe you approve people super fast.
