I almost got my nephew labeled as a sex offender, because at age 11 he pulled my daughter's pants down in an argument. Not as any kind of sexual thing, but to tick her off. She was four at the time. My wife and I called some childcare 'hotline' for advice on how to deal with the issue, because it wasn't the first time that he had used this tactic to run her off. The operator told us that if he was 12, he would have been obligated under law to report our nephew as a potential sex offender, which would have certainly caused a visit from Social Services.
I have no words to describe how stupid such a thing is... unbelievable!
Back to the topic... what's actually the point of us discussing this here? I mean, it's up to the owner(s) of SilkRoad to decide it, and as far as I know, s/he hasn't even asked our opinion on this matter.... (unless I've missed something).
If your point is just discussing how you think the ideal anonymous market should behave, and you don't think SilkRoad is being this ideal anonymous market of yours, then think about competing with them.

I realize it's not easy, but I guess it's more effective than discussing stuff here at least.
