VanguardGarrison, this feedback is vague and misleading.
I don't see how the blackness in the boots contribute to the rest of the article. I'm not saying to remove it but maybe just find a way to relate it.
In this case, given how casual "nothing but pure blackness" comes off as, it would be better to just remove that part entirely. Additionally, since nearly an entire paragraph is devoted to describing the blackness even though that's not the primary anomaly, it can be distracting for a reader if that's the first information they're presented with.
I think the idea is pretty solid but I think you need to elaborate on it a little bit more.
I'm going to disagree—this is a pretty garden-variety magic object approach, and "things that kill you somehow" are submitted many, many times each week to the mainsite, only to be downvoted and deleted. The fact that this thing is apparently so complicated and has a cliche expunged backstory that can be made hilarious with a few assumptions is also problematic (author, I recommend reading over this guide on interesting expungment for some tips).
Furthermore, how does the Foundation know that there's any sort of "judgment" going on at all? How do they know that there's an entity in the boots as opposed to the anomaly being just the boots themselves?
Keep in mind that as the author, you know the entire story, but the Foundation needs to have discovered what it knows about the SCP object through observation and experimentation. You'll need to convince your reader that someone with no prior knowledge whatsoever of the anomaly managed to somehow figure out (not magically know!) all the information you've got in the article.
Maybe write a couple more experiment logs or something along those lines.
For the record, tacking on extra experiment logs just for the sake of having more logs can bog down an article with repetitive or uninteresting text, which makes it worse overall.
OP, this draft is heavily problematic and likely will not do well on the mainsite as-is. There are many more nitpicks I could have made, but at this point it's much more sensible to work on this concept than attempting to fix up the draft while the idea still isn't good.
I recommend getting the base idea polished up in the Ideas and Brainstorming forum before you try fixing the draft. Go to that forum, post a quick summary of the concept you want to write up (don't link the draft unless someone asks), and reviewers there can help you make the idea more interesting and give you some advice on structuring the eventual article for smoothness of reading and narrative.
