I just verified this myself. It is completely true. Actually, I lied; it is mostly true. The only difference is, for me Bing shows “how to commit suicide” as the first (not second) instant search suggestion when I type in “how to com”.
The irony here is Bing gets a lot of crap for more adulterated search results than Google. But if you think about it, in this situation Bing is providing less censored search by offering “how to commit suicide” in instant search and not directing people to a hotline. However, this may be a case where less censorship is not the more desirable option.
