SCP Foundation

to a Foundation employee of Clearance Level 4 or higher.

Even though it's under a strikethrough, I would re-word this a bit… "a Level 4 or higher Foundation Supervisor"

SCP-XXXX-1 disguises are near-perfect, and serve the function of their disguise as well as recording their surroundings.

I have problems with the wording of this line, but I don't know what you can do to fix it. It's like you're trying to put two different concepts into one thought.

However, they are rooted in the ground, and resist attempts to pull them up. If enough pressure is applied, however, an instance can be ripped up, tearing wires which root it to the ground.

Overuse of the word "however".

If an instance is torn up, the wires will retract into the ground and recede back to where they came from.

How do we know they are going back "where they came from"?

It is theorized that each wire connects to an instance of SCP-XXXX-1, allowing data from one instance to be transferred into another instance, and therefore to all instances, creating a "web" collectively dubbed SCP-XXXX.

Why would this be theorized based on the discovery of a few instances of items with wires coming out of the ground? I don't follow the logic.

This can be seen, as a single instance can contain over ███,███ terabytes of information.

Ok. How is the Foundation determining that it contains that much data?

This is achieved by having an apparent spatial rift inside of a SCP-XXXX instance:

Why would a spatial rift enable extra data storage? Data is ephemeral, it does not exist in real space as itself. If you look at a CD, you don't see the data, you see little pits where the laser has etched the surface. If you look at a hard drive disk, you don't see the data, you see magnetic particles deposited on a platter.

Any information beyond approximately 3 seconds into the past disappears off the physical instance and is stored in a larger hard drive in a separate place instantaneously.

Again, how does the Foundation know this?

When attempting to obtain information off an instance, the instance must draw upon the larger, separate drive and feed it back through, exchanging that with more recent information.

And again…

It is theorized that the original creator of SCP-XXXX had a simpler method, a sort of collection receptacle for all of SCP-XXXX.

And again…
This is a lot of expository information that I don't see how the Foundation could have discovered simply by examination of found instances of SCP-XXXX.

A yield sign on a stretch of freeway outside my house.

If the disguise is so perfect, why would there be a yield sign on a freeway? It's so obviously out of place that it seems as though it's almost begging to be discovered.

Any knowledge of SCP-XXXX is to be repressed from the public via memetic agents and widespread administration of Class B amnestics if large populations gain knowledge of SCP-XXXX.

If SCP-XXXX-1 manifests itself in an easily noticeable location, public knowledge is to be supressed with aforementioned methods…

This seems redundant. If those methods were already mentioned, there's no need to bring them up again.

Special Containment Procedures: Iteration 1: IRRELEVANT Any knowledge of SCP-XXXX is to be repressed from the public via memetic agents and widespread administration of Class B amnestics if large populations gain knowledge of SCP-XXXX. Previously undiscovered instances of SCP-XXXX-1 are to be reported to a Foundation employee of Clearance Level 4 or higher. If SCP-XXXX-1 manifests itself in an easily noticeable location, public knowledge is to be supressed with aforementioned methods, and destroyed as soon as possible.
Iteration 2: IRRELEVANT Any knowledge of SCP-XXXX is to be repressed from the public via memetic agents and widespread administration of Class A amnestics if large populations gain knowledge of SCP-XXXX. Any and all instances of SCP-XXXX are to be reported to SCP-XXXX Project Directer, Dr. ████, and destroyed as soon as possible.

I think it's overkill to strike out the old procedures and mark them IRRELEVANT in bold all-caps. You could just put them in a collapsible.

It's not immediately apparent what changed between the two iterations. The second one might work better as an addendum to the first.

Also, everything here is struck out. There ought to be some current containment procedures, even if it's just something like "As SCP-XXXX has self-neutralized, no further containment is necessary".

Instances also have a minor memetic effect on humans, causing them to not notice instances where they should not be.

"Where they should not be" is kind of vague, especially since security cameras are often hidden or disguised in real life. How do people know that there's something anomalous about the cameras? If I found a camera disguised as a Yield sign, I'd just assume the police were using it to catch speeders.

Simply pointing out that an instance of SCP-XXXX-1 is somewhere it should not be is usually enough to cause a human to recognize odd qualities of the instance.

Again, I'm unclear what the "odd qualities" are. So far, they just sound like disguised security cameras, which aren't all that odd.

If an instance is torn up, the wires will retract into the ground and recede back to where they came from.

We don't actually know where they come from, right? So this part doesn't really make sense.

SCP-XXXX is a phenomenon in which an instance of SCP-XXXX-1 will appear in a seemingly random location across Earth.

It is theorized that each wire connects to an instance of SCP-XXXX-1, allowing data from one instance to be transferred into another instance, and therefore to all instances, creating a "web" collectively dubbed SCP-XXXX.

These seem to contradict each other. Is SCP-XXXX the phenomenon of cameras appearing, or the web that connects them?

It is theorized that the original creator of SCP-XXXX had a simpler method, a sort of collection receptacle for all of SCP-XXXX.

Why is this theorized? For that matter, how do we know there was an original creator? It could be an independent organism.

SCP-XXXX was first discovered by the Foundation on ██/██/20██, when a Foundation operative found the home of █████████ ████ in █████, Kentucky.

What drew their attention to this home? Operatives can't stop to investigate every house they drive past.

█████████ had managed to get ahold of a fake yield sign that was actually an instance of SCP-XXXX-1.

The tone feels off here. "get ahold of" sounds informal; maybe "obtain"? Also, "a fake yield sign that was actually an instance of SCP-XXXX-1" is kind of clunky. You could say "an instance of SCP-XXXX-1 disguised as a yield sign".

Anyway, I went right up to the goddam thing and kicked it out of anger, and a couple sparks flew out! On a yield sign! What the hell is going on?

I don't think real electronics do that. Maybe wires could pop out, but I don't think they'd spark.

And the bottom of it was… wrong.

This is vague and a bit cliche.

██/██/20██: i doont remember th[UNINTELLIGIBLE] beiing like this

██/██/20██: STOP [UNINTELLIGIBLE]E

██/██/20██: [UNINTELLIGIBLE]

██/██/20██: HELP ME [Note: This is the most recent entry]

So… what's actually going on here? Were there signs of a physical struggle? The Foundation would've investigated the area for clues about what happened to him. Even if they didn't find anything, that in itself is notable.

…and keeping GOIs in line.

This also sounds informal, especially since it's coming from the O5 council.

There are discrepancies. Very minor, very small, and maybe one or two very large ones.

Why doesn't he describe the discrepancies? That might be a way to hint at this thing's true motives, origins, etc.

Someone out there is changing everything that's coming through the cameras, even if by accident. Someone is reviewing every single tape.

How do they know someone else is doing this, rather than the cameras themselves?

Think about what happened to the last guy who found out about it.

But we don't know what happened.

im still here you cannot win i am eternal i cannot be destroyed

I think this secret message is the biggest problem right now. It's too generic. It doesn't really add anything beyond "I'm big and scary". When it says "you cannot win", what does "win" mean? So far, it's just been observing us and messing with its file. We have no idea what its long-term plans or goals are.

Also, why did it send us this message in the first place? Does it get a kick out of scaring SCP personnel?
