Whether you believe it or not, child slavery is a real issue in a lot of countries over the world. The point of the chat was that the exchange should try to prevent any illegal trades beforehand, so a tiny part of it must be centralized to disallow of some product groups. "children" was just the worst example we could think of, but it also refers to "heroin", "plutonium" etc. Dan was not accusing any specific person of wanting to do such trades, he was mainly pointing out that there are people out there that want to do it, and eMunie is not for them.
"[7:25:46 PM] Dan Hughes - eMunie: They can complain, the complainers are the ones that will get us into trouble selling children"
My problem was not with whether child slavery is an issue. It was with Dan suggesting that the complainers (e.g. me) had nefarious intentions. He basically said that if you have a problem with how he's planned things, then you are obviously a criminal wanting to use the system for nasty things.
It's a cheap way of discrediting your critics.
I hope you can see the difference.
