Likewise you don't need to invent a knife-over-IP protocol to use the internet to help kill people.

You can order bullets on the internet.

Does this fall under the banner of 'use the internet to help kill people'? Your facetious post and response seem to imply that you had something more specific in mind, or perhaps something by a specific group.

My point is just that "you can't directly do it over the internet" applies equally to both examples, so you need something else if you want to distinguish them.

Sites that facilitate sex trade / crime are direct actions in the trafficking chain. It happens on the internet. No, the john doesn't come through the tubes, but his order does. Directly over the internet.

What was your example again? You keep referring to it, but I can't find it in the comments, which makes i thard to see how your point applies equally.

The other example was Nazis getting together and beating/murdering people.
