I have no idea how these even happen, but here's a bunch of blank entries by dravensth:
User uploaded 3 large photos to the site when making this entry:
https://vgcollect.com/item/157646There ends up being a time delay on item creation when a large image is added to a new entry, because the site has to first save the original image, then load it into memory, resize and create the smaller image that is put onto the entry, then it will delete the original image. It has something to do with that, or perhaps they had hit back and resubmit, or refresh during that process.
I'm genuinely curious to know how entries like this one happen...

Apparently nobody created it.
There are two main reasons why you would see NA on an item author:
1. If it is a low number entry, the site was originally populated with data from a few sources when it first started (this is my understanding) and these entries that were made this way do not have an author.
2. A user had deleted their account after making the entry or edit.
There might be some other way for it to happen, ideally we should not be having this empty item issue.
