I was amazed (and still am) at the number of people that trust anonymous nicks so when I opened a mining pool I put my name and business details in the first post.
Bitcoin is supposed to be anonymous. What's wrong with anonymity?
Anonymity is generally bad for business when there are two-way obligations. You can't file suit against "fogducker666" unless you know his name and location. It's generally also a bad idea to do major amounts of business with someone far away, because again, you lose the ability to file suit. Maybe more importantly, you lose the ability to threaten filing a suit. Moral or not, the government is force, and nobody wants to be on the receiving end.
It's kind of funny, though, because Bitcoin's fairly small, and there's a large forum community. Bitcoin's advertised as "zero-trust," and I guess people expect mods and admin to review and remove scams pre-emptively, or maybe just for the community to be pretty close-knit, not scamming each other. So, "fogducker666" shows up selling LSD behind a Tor website, and a good few people will send him their BTC before it's realized he's scamming.
