Consider this: if the providers of these suicide hotline numbers actually cared about this stuff, they would provide an as pseudonymous as possible way to contact them that makes it as impossible as possible (in a mathematical/cryptographical sense) to identify the caller (think about Tor).

Additionally, the hotline operators would advocate very strongly for a right to encrypt and right of privacy.

But this is not the case, which should convince any rationally-thinking person that all of these claims of anonymity are fraud.
