From a literary journal’s submission guidelines:

We do not ever accept unsolicited submissions of art, novels, novellas, novelettes, or anything else longer than 5,000 words. If you submit a novel or anything way over the word count limits, we’ll probably blacklist you.

This isn’t negotiable, so don’t ask. If you need to have these things in your story, find a different market. We really do have a blacklist.

Somehow, I believe you.
