I knew a few people who had a "if you read this, I am dead" cronjob setup on their machine: if they wouldn't log in by a certain time, an email would be sent saying that they're dead. Of courses there were cases where people would simply forget about these cronjobs and send email needlessly worrying the people they cared about (and possibly getting themselves 5150'd).
What about "If you are reading this, there may be a serious problem. I usually log into my system everyday and since that hasn't happened, please call or try to find me to make sure I'm OK"
That way it's only slightly alarming to your loved ones.
that's different, but do you really need to worry the people you care about like this? bad news travels fast and if you do need to call for help there are ways slightly more person than a cronjob (though this sort of a cronjob message won't get you 5150'd, which generally makes whatever problems one has worse).
Yeah. If there is a reasonable suspicion that someone has attempted/wants to attempt to take their life, the police will take you in and do a 72-hour hold.
