Your decision seems very obviously wrong to me. I don't want to overrule you directly without further conversation, but I don't understand at all why you unbanned the post. There's a forum for ridiculously terribly written fanfiction, and it's fanfiction.net which is famous for taking everything. The post is of quality less than zero. Why should it be here?

But really, I wouldn't think a lighthearted parody of a lighthearted parody would cause such offense.
The original post has been unbanned and can be found here, so I've edited this post to just be about the banning.
