"Faces of Death" tapes made someone some money back in the day (which is to say the 80s).
I don't know why people always feign shock about this. We're less than a century from public executions being a form of entertainment in this country. There's barely a layer of topsoil over the sentiment.
Also, he's doing it wrong. Asking people not to click only drives traffic their way. Asking people to write the sponsors (or wherever their money is coming from) and inquire if they want their brand tied to videos of people dying is the way to get it buried.

Not the same, but how many clicks did you guys squeeze out of Macklemore Nosegate 2014?

You should have stopped at "this isn't censorship". I have this argument with my dad all the time about the Washington Redskins' name. Asking the owner not to change the name or boycotting the team or whatever is not censorship. Nobody's making him do anything. Just like with the tweet from Louis C.K. Nobody's constitutional rights are being stepped on here. Calling people out when they're assholes does not violate the first ammendment.

"Does this article from The Stranger support censorship?"
"The one weird thing Paul Constant posted about today"
"You won't believe what a Seattle newspaper said!"

Agree with @8.

Drives me fucking crazy sometimes. This isn't censorship, full stop. This is not the government infringing on someone's free speech rights. Does nobody understand what censorship means anymore?

Came here to say what @8 said. Individuals acting in a free market to try to persuade a news outlet (or a news-ish outlet like Gawker) to be a bit more tasteful is different than the state using its power to block expression or to block publication. This isn't censorship. Calling Louis CK's tweet a call for censorship is just as inaccurate as when right wing Christians complain about being "censored" when the rest of us push back against them talking like bigots.

Whether it's a good idea or a waste of time is another question. Gawker's gonna gawk.

Lewis Black also put out a request via Facebook (at least that's the one I saw) to not view the video on TMZ. It's not censorship to ask people to not view it. It'd be censorship if someone with authority over TMZ, like the gov't or their bandwidth provider, pulled the video down against their wishes or blocked it from view.

I agree. Merely asking people to be considerate compassionate human beings isn't "censorship."
