Too Strict With Child & Sex Keywords?

The Hammer of Trust writes that is way too strict for searches on keywords about sex and children. For example, a search on on [laws against pedophilia] brings back a message that reads, "This query does not comply with Terms of Service." The "Go" button following the message links you to Terms of Service. Other similar searches do the same thing, such as , talking to your children about sex, blocking porn from kids and warning your kids about sex offenders. I also tried searching on preventing child pornography and that also was blocked.

It is important to note that all these queries bring back results at both Google and Yahoo. Is way too strict here? It appears that way. But is it better than being hit with a child pornography suit like Google was?
