They run through a litany of NGO complaints, basically presenting one side of the debate. However, as early as January of 2016, I had addressed many of those complaints elsewhere [1]. By April of 2016, a respected anti-wildlife trafficking NGO even declared that "it would be rash to rule out the possibility that trade in synthetic rhinoceros horn could play a role in future conservation strategies [2]." Things have only improved from there [3]. Yet, "what's controversial" turns into "what's false" on Snopes. After seeing how the sausage is made, there is no way I'll ever trust them.

In the future, I would recommend disclaiming potential bias through your profile or on the comment itself. Otherwise, commenters who skimm may be misled and commenters who read may question your authenticity.
Please note that my conflict is not with Snopes, it is with the NGOs and their statements, which Snopes chose to solely feature.
