Closed to submissions until 1st August because they "just signed a 9-book series".

Wow. Looks like they decided to be a lot more professional in their responses after I practically taught them how to give a response that didn't look like the bitter rants of a teenage internet troll.
A whole lot better than providing an example of a single instance where an unnecessary comma was left in after an edit and the response was:

"embarrassing."

followed by::
"If you genuinely do not know that the comma there is an error, I suggest reading a book.
Seriously, you're lightyears from submitting to a publisher."

Rejection after two days but was helpful. 111000 Fantasy

Thank you for the submission. I really like the premise here, and I think it would make a very successful LitRPG. As it stands right now, the mechanics of the writing need a lot of work. Specifically, a lot of the dialogue tags are grammatically incorrect and / or very repetitive. If you're willing to take some notes on editing and then resubmit, I'd be happy to take another look. Just let me know.

I second what Anon4453 said. Their idea of personal response is a condescending and snarky response, and if you look for any sort of clarification, they become downright insulting. I would not recommend wasting your time with this so-called "publisher". Extremely unprofessional.

I should have been skeptical the moment that I saw that their company address is just a gmail account.

This is not a legit publisher. It's a group of friends self publishing their own work under the guise of an actual company. They will not offer actual feedback, but they will insult your talent and quality of work. There has never been a single approved query through this false publisher, because they have no intention of doing so. It's a complete and utter fabrication and no one should waste their time with Nef House.

The owner publishes his own books through his own company, then rejects all submissions with zero intention of actually publishing anyone else's work aside from his friends. This is just self publishing with extra steps.

Ironically, all of the owner's books are poorly reviewed.
