Oh that is totally untrue. There is something fairly obvious you could do: Don't attack people with viral tools in the first place.
Anything that intentionally adds overhead to the other person, without adding value to them, is an attack. How many people can you possibly think would want to advertise your service for you - and need your words to do it? You think if people really want to share your product they're going to develop a sudden writing difficulty?
You know as well as I that people don't read everything - we have finite attention, we do things in a hurry. And you exploit that as an attack vector for your nasty advertising stuff.
You're acting against the other party's interests from the off and you want to what?... Make it seem okay somehow? I suppose strictly speaking it's better if it's the way you say it is than some other way - but it's like saying: "Well, strictly speaking, I only murdered three children. Not the ten everyone said I did."
Checkmate. She can't worm her way out of that.
