The fun thing about this site is that everyone has 1 vote. The guy who runs the site, the admins, the veterans, and the guy who joined yesterday all have just one vote each. So "I don't like it" only means "I don't think it's a good article"
More specifically, I usually don't vote on articles where I dislike the concept but the writing is good. Here I dislike the concept and the writing isn't up to par, so it would be a downvote from me.
That doesn't make it objectively bad. And as the guide to writing an SCP states: "There is no such thing as a bad idea. Only poor execution. If someone tells you your idea sucks, that's their opinion. It means your execution wasn't good enough to convince them that your idea had merit. Try again."
If I had a gun to my head and had to write an SCP with this concept, I'd give it some purpose, or have something cause the effect with some purpose in mind.
I'd probably go for an animal/bacteria that rearranges your body to suit its needs. However, "things what lay eggs inside you" is a tough cliche to write for, and it would probably brush up against SCP-439.
