I think it makes good sense to continue to publicly discourage people from buying these species, and I support that policy. The recommendation from one or two field scientists to protect these species came along with sound reasons: limited habitat and range, easily accessible to collectors, high prices (which strongly supports the claim of rarity), and the inability of rearing them in captivity (small egged).
That being said, I think that we have a responsibility to protect the integrity of Tonmo.com as a source of accurate information, and to protect the credibility of science and scientists by resisting the temptation to exaggerate. I think there's a real danger that the public will learn to distrust (and ignore) scientists if they too often compromise truth for the sake of any "greater good". When people read a blunt statement like "Get another species, one that is not endangered", and after a little looking discover that the truth is that there is reason to suspect that increased collecting pressure might be devastating, they will realize that they've been purposely misled, and be much more likely to ignore such statements in the future. In this way, exaggerations that erode the credibility of environmental warnings, puts all endangered animals at greater risk, and in the long run are counter productive. We've got to tell the truth, or we'll be ignored, and endangered animals will suffer.
