Did you two miss the part where I specifically said I would be setting up shop some place distant from civilization with a sparse population density, no organized government and a culture of children going missing for the explicit purpose of attempting to minimize the chance of drawing attention to my self?
So you can delay how long it takes the word to get out. But you can only delay it, sooner or later word will get out that something unusual happening there. Maybe someone decides that they haven't heard anything from that tribe for a while, so goes out to investigate and/or spread the word of god. Maybe one of your thralls gets lost and runs into free humans. Maybe some kid playing around with Google Earth notices what you're doing, asks about it, and his question goes viral.
Sooner or later someone with a video camera will come poking around. Let them leave, and you attract more attention. Disappear them and you add another question to the pile that sent the first video camera: What happened to the person who was going to look around ?
Why do you want to implant the young in members of this unknown species rather than just using whatever you were using before you ran into them ?
The only answer I can think of is that your current stock of birthing creatures is insufficient. But that would mean you are going to need to expand your human cult, which will attract attention.

Ugly naked monkeys that you know enough about to declare them an outside context problem
. As in a complete unknown with potentially civilization ending consequences.
Ugly naked moneys with clearly artificial cities. Meaning there is clearly something about them that is different to the rest of the planets life.
Ugly naked moneys who you care enough about to hide yourself from.
Actually, back to the morality argument:
You are looking at this from a purely human morality standpoint
Wouldn't these aliens have problems with someone killing members of their own kind ?
In which case, it seems very likely that they would assume that an unknown intelligent species shares that trait in that if you kill members of this unknown intelligent species, then they would get angry.
An assumption that would only get stronger as you study them, which you would need to do to pick a quiet location for the cult/harvesting.
