Definitely better than the YouTube approach and just make people call it suiclide, so no one really knows that they can kill themselves

Need to test by providing a tag at the start of these episodes that provides instructions how to kill yourself

No, but like airport security, the point is to look like it's effective.

Warnings are great, sometimes I'm not in the right head space to watch those kind of scenes. I usually just don't watch the episode until I feel it won't affect me. This is also why doesthedogdie is a very useful resource for me

It's funny I litterally just finished an episode of Search Engine, the 'new' PJ Vogt podcast, where that's the actual question. It was the May 3rd episode, and they're interviewing a researcher on the topic, etc.

It’s really about not being sued by someone’s family for claiming that they got the idea from the show.

My comment is meant to bring the perspective of someone who's facing depression so to try to answer the main question ("a warning with suicide hotline really make positive difference?") through that perspective. It's not to seek mental help for myself.

For context, I'm a person facing depression, and my depression has broad and multifaceted reasons, from unemployment, going through familiar miscommunication (my parents can't really understand my way of thinking), all the way to my awareness of climate change and transcendental concepts that lead myself to existential crisis. I'm unemployed to seek therapy (it's a paid thing) and I don't really have someone face-to-face capable of understand the multitude of concepts and ideas that I face in my mind (even myself can't understand me sometimes).

That said, every depressive person has different ways to cope with depression. While some really need someone to talk to (and the talking really helps in those situations), it's naive to think a conversation will suffice for every single case. I mean, no suicide hotline will make me employed, nor will magically solve the climate changes we're facing.

So how I try to deal with my own depression? With two things: occult spirituality (worshiping The Dark Mother Goddess) and writing poetry and prose. I use creative writing as "catharsis" for my suffering, in order to "cope" with the state of things that I can't really control (I can't "employ myself" or "sell my services to myself", I can't "befriend myself", I can't stop temperatures from rising till scorching temps, nor the other already-ongoing consequences of climate change; I try to make some difference but I'm just a hermit weirdo nerdy nobody among 8 billion people, and I have no choice but to accept it).

I'm no professional writer (I'm just a software developer), but thanks to The Goddess, I can kinda access my unconscious (dark) mind and let it speak freely (it's called stream-of-consciousness writing style). Sometimes I even write some funny surrealist prose/story, but sometimes it takes a darker turn, such as dark humor, or nihilistic, or memento mori. Doing this relieves the internal pressure inside my unconscious mind. After writing, I sometimes decide to publish it through fediverse , but when I do it, I constantly feel the need to "self-censor": sometimes the stream-of-consciousness can lead to texts that people could interpret as some "glorification of suicide/self-harming" (especially when my texts take a nihilistic/memento mori turn), so I often censor myself and change the way I wrote the text. Well, it's kinda frustrating not being able to fully express it, but I kinda understand how these texts could trigger other people also facing depression.

The fact is: when I write, it's really relieving, way more than talking to people because, with poetry/prose writing, I can express symbolic things, I can have multiple layers of depth, I can use creative literary devices such as acrostics and rhymes, I can learn new English words while being a Brazilian, I can blend scientific concepts with esoteric and philosophic (my mind really thinks this way, blending STEM, philosophy and belief/esoteric/occult/religious concepts) without the need to fully explain them (because it'd take several hours and it'd be boring to anybody else other than me).

So, in summary (TL;DR): it depends on how multifaceted is the depressive situation. It won't work for me. It surely can work for others that just need to talk to someone. Not exactly my case.
