First of all, SE's policy is "In case of doubt, help out", as I've pointed out in the link to their official reply
Second of all, the policy exists because they don't want to become the kind of place where people come to discuss things like "How do I run away from a hotel without paying" or "Where can I buy a fake driver's license". This gets on the news and - bam - StackExchange is now "a site for criminals"
