Does animesuki have issues with me posting an original work web ficton/novel here?
 

I wrote a thingy, kind of isekai ish with tribal and garlic myths with power progression and kingdom building.
If I were to post it here in a thread like sufficientVelocity forums, would I get banned?
If not, which section should I post it in?

I think the Fan Creations subforum is your best bet.

Infinite Zenith is right. Fan Creations is where your work should go.
