My first experience with craigslist was trying to figure out why they had the capability to block my wife's ad for a free dog that contained a mispelled word while the site's creator was busy trying to tell the government that there was nothing he could do about the many child prostitution ads that appeared on craigslist.
It sounds like you ran afoul of the fickle community moderation. The last time I checked, CL doesn't block ads, they just get flagged off by regular users.
I would think that these ads aren't exactly to-the-point considering what is offered is extremely illegal. I sincerely doubt you could reliably identify them based on keywords alone.
If it were so easy to spot child exploitation ads, why doesn't the police or the FBI monitor sites like Craigslist? I'd much rather see the people involved in that filthy business prosecuted than simply having their ads blocked (which doesn't do anything for the victims).
