Not sure how to be more successful with Goof submissions

Out of 4 Goof page edits I made for Seinfeld, only 1 was approved. I read carefully through submission guidelines. I thought I had a done a nice job. The reasons I was given for the edits being declined was they either didn't meet guidelines or there was no way to verify what I was saying.  I understand the subjective nature of the guidelines, but I'm really surprised about not having a way to verify what I'm saying. Just watch the part of the show I'm mentioning! Of course there's a way to verify it!

The standard declined-submission response mentions that I can attach more detail in an explanation field and resubmit.  I was very detailed the first time and there's nothing I can think to add that would help, except for images and video showing what I'm talking about.

My question: why aren't photos and videos allowed as supporting evidence for page edit submissions? At least let us link to media.  Then the reviewer sees what we're seeing and can go verify the goof exists in a trusted source for the show or movie.
