Wish I didn't think laws like that were a good idea, but after dealing with the ex-wife's psychotic episode and threats to kill our child I did some digging and discovered that maternal infanticide is terrifyingly not as rare, and that it's generally not counted as "murder" for statistics purpose (many countries have separate statutes which cover it).
Over the course of your life the people most likely to kill you are: yourself, your mother, your father, some step parent, some random person. Though if you make it to 5-6 years the parents stop being as big a threat.
Web sites and pages come and go, but the search engine indices are forever. The Internet Archive, for example, uses data from a search engine crawler to populate their archive of the internet (until Alexa was shut down by Amazon, they do their own crawling now). Google likely has a lot of old internet data in archives as well.
