… prevent claimed users (which/who are in fact bots)…
In the above sentence, what's the most appropriate choice to refer to the users that are in fact bots? I think, which is correct one, however I'm afraid of grammatical mismatch. Of course, using that can solve the problem, by the way.
Use it for humanity:
“Humanity lived thousands of years in an environment without any source of electric power, but in an environment with radiation it will be dead in a few days.
However, to my ears, “Humanity” sounds more like “the state of being human” . She showed her humanity when she cared for the wounded.
For the sentence in the question, I would suggest:
- "Humans" - they, their (Humans are highly social beings, and they have their own...)
- "Mankind" - it, its (Mankind has been around for over a million years.)
- "Humankind" - it, its (for those who dislike the term "mankind") (How long has humankind been around ? It has….)
- "People" - they, their (People will be dead in a few days if they are exposed to…)
Strictly speaking, one transmits over a channel:
In information theory, the Shannon–Hartley theorem tells the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise.

In practice, you'll find that both on and in are also being used, albeit less frequently:
However, there may be a nuance: for example, a TV engineer might say my station transmits on Channel 5, but we are now transmitting a test in our UHF channel.

I think you can use either and it would be acceptable. However, you already anthropomorphized them by using the verb claim, so it would be consistent to use who to refer to them. If you changed that phrase to something less active, such seemingly human users, it would then be more appropriate to use which.
