I wouldn't want to comment on the quality of the methodology but the ethics look fine to me. I would say it is rock solid.
If I had the resources, and some boiling bleach, I could probably achieve the same result. Especially if combined with high doses of radiation, a very shiny hammer, and a rubber duck. I would tend to agree with the OP - this isn't science and as such.....
