Hey there, I am not an official reviewer, but I would strongly suggest not posting this SCP on the site yet. I've had a look through and there are some large problems which I think you should consider addressing:
- Readability: I found this SCP very hard to read, mainly because of the amount of "technobabble" (as you say earlier in the thread), and the minutiae in the description. To me, a lot of the extra information about the object that you've added doesn't really add anything to the piece, except making it hard to read. I would suggest that you simplify a lot of the descriptions and wording overall.
- Core concept: I found it difficult to see what the core idea of the SCP was under all the information. I found it quite confusing. What I eventually took from it, was that it's an unknown crate which has sheets of sentient entities which become "attached" to people and follow their orders. Plus, there is some kind of terrible biohazard at work. Plus, there is some unknown stuff happening in the redacted sections. I felt like it was a jumble of ideas that was hard to get my head around. Perhaps you should focus on one of the ideas, or at least separate them into distinct sections to make it clearer.
- Redactions: There are a lot of Redactions. Redactions can be effective when used well, but it's a tricky balance. Here, I felt like they were covering up too much information to make me care about what was under them. There is little mystery when so much is hidden, because I don't have enough clues for me to even get a sense of what might be under there - therefore it's not intriguing to me. Also, the containment procedures have some big redactions in them. This is generally a no-no, because all foundation personnel need to know how to contain it.
Overall I would suggest doing a ruthless cut of detail in this piece to start off with. I think once it's in a state where it's more readable, and shorter, it will be easier to home in on the other issues, and identify the main concepts you want to bring out. I feel like there could be some interesting ideas in there, it's just very hard to pick them out from all the details.
Note this is just one opinion, so before you go ahead tearing your draft apart I would get some more. However I firmly believe it does need a cleanup before you should even consider posting.
