I don't know if that title is worded well, but I am curious if there is a word or phrase that explicitly refers to: if you have the "power" (hypnosis, brainwashing etc.) and you control someone and instruct them to bring you more people to control and gather even larger groups, It's not hypnotized hypnotist, because the hypnotized individual doesn't do any hypnotizing, nor is it memetic control but it has Memetic's potential for exponential growth... or would a bunch of tags be applied that cumulatively refer to the above (ignoring the fact I am not trying to tag anything, just using this site's term)

I don't think we have a tag for it here, but I believe the term is "serial recruitment."

What you've described is sometimes referred to as "falconry".

That might be correct but it's far from intuitive. At least with 'serial recruitment' I could work it out without looking it up.

despite you protesting it's not, for the hub at least, this seems to fit the "memetic_control" tag

General: memetic control
A subject is controlled to control others in a self-propagating fashion. This has a lot of overlap with hypnotized_hypnotist; however it has two major distinctions:

There should be a strong implication that the sub may go on to control others, who themselves may then go on to control yet others, etc. This can be described as a "memetic" or "viral" spread of subs. Typically this spread creates subs that are copies of each other, possibly by creating an identical mental state, if not by outright transformation.

This tag can apply when the dom of the image is not under any kind of control, as long as the image strongly implies that the sub will go on to spread control as previously described.
