I like the addition to the first one, though I still think it needs a little bit more added to make it creepier. An incidence report would definitely do the job if done right.
As for the second one, once again its a cool idea but it needs a bit of reworking. First off, "Memetic Molester" sounds more like the name of a superhero/supervillain than an SCP. Mememtic Predator would probably work fine, or something else like it, but the alliteration just makes it a little silly.
Next, minor thing, above the list of signs that someone is infected, you have [EXPUNGED] instead of [DATA EXPUNGED].
Also, I agree with DrBobson, "expunging her data" is almost comical. It sort of ruins the tone of the whole article.
Lastly, and this is up to you, I personally think that overall this SCP is just too graphic. In most of the SCP's I've read, exceedingly graphic parts are cut out with [DATA EXPUNGED]. A great example is SCP-231. It is creepy and messed up and depraved, but all the truly horrific bits are expunged. You can even do things like "Then he procceeded to [DATA EXPUNGED]. He even made the fucking son watch!" I just feel like the graphic level of detail included, especially about targeting little girls and cutting up his own face while raping a woman, are just too over the top for what is supposed to be a somewhat detached, clinical report.
This is obviously my own personal opinion, and I am pretty new to the site, but there you have it, my two cents.
