I realize that some of you with vested interests in this area may consider this an assault on your rights of free speech. However, there are specific rules. These rules are designed to protect innocent and unsuspecting members of the community.
The topic is the summary. I could go on about how bitcoin is young and needs to be protected, or how recent events regarding lending have shaken the bitcoin economy. But that's not a very persuasive reason to those who stand to loose money.
Basically, I am sure some of you are aware that countries(and even local rules, example US states) have strict rules about marketing, dealing and/or offering these products. If bitcoin.org wants to avoid being associated with fraudulent and illegal activities, it should move quickly to remove certain categories. These categories have allowed entities to offer products that potentially violate US rules. At the least it should ban open topics regarding offering these products to US based bitcoin members.
I realize some of you who post and have an active interest in these areas might think this is too harsh a preemptive action. However, these examples that should keep the moderators up at night: craigslist, megaupload, Full Tilt Poker; at the minimum Mt. Gox implemented Anti-Money Laundering and Know Your Customer rules, common to US financial entities.
Some of you may argue that bitcoin's are a virtual currency and is above the law. Be careful what you wish for, because so far above the law has meant lots of fraud.
Edit: Sorry, I meant BitcoinTalk.org, referring to this site. Thanks to Stephen Gornick for pointing that out.
