I had an odd experience some time ago. For curiosity I performed a Youtube search for a video on How to make a Hangman's noose with a rope, the search result yielded a big message on my screen pleading me, the viewer to immediately call one of a number of Crisis centers for help.
Presumptive but Understandable.
Someone in YT was thinking ahead just in case.

By now I forgot how to make a Hangman's noose.
