No this is a filter. It is the same reason why the wife of nelson mandela has millions to give. Any interaction after initial spam cost time and hence if there is no return it is lost opportunity. Best victims are the ones which are not aware that there is a scam at all. Overseeing bad spelling correlates with inability to read carefully which correlates with being with bad intelligence. So people answering very bad spam are in fact more likely very good victims.
To be honest all this skin cancer detection stuff is kind of non-proven to be effective. Problem with this is that it leads to overtreatment and a non-measurable prolonging of life-time.

And then what is more unhygienic?
Feces, urine on the floor or feces, urine all around your bottom? For the first you can use almost any cleaning liquid you want, for the second even to much soap is not good.
The argument for and against reusable is pretty much undecided. There also services which do the washing for you. And they are probably way more efficient than people washing at home in terms of energy used.
Anyhow, real eco-parents go diaper-less as most parents in the world. Google split-pants, elimination communication! Compared to this letting children sitting in their own feces in reusable or not-reusable nappies is pretty unhygienic.
