Oh come on, you are evoking your basilisk-related logic here? How does it have a negative effect. Please don't tell me that it is because you think that there will be more suicides in the world if the number of readers of the post is larger? And further please don't tell me that if you thought that you think that this will lead to a net negative effect for the world? But please do answer me.
It has a net negative effect because people then go around saying (this post will be deleted after policy implementation), "Oh, look, LW is encouraging people to commit suicide and donate the money to them." That is what actually happens. It is the only real significant consequence.
Now it's true that, in general, any particular post may have only a small effect in this direction, because, for example, idiots repeatedly make up crap about how SIAI's ideas should encourage violence against AI researchers, even though none of us have ever raised i...
New proposed censorship policy:
Any post or comment which advocates or 'asks about' violence against sufficiently identifiable real people or groups (as opposed to aliens or hypothetical people on trolley tracks) may be deleted, along with replies that also contain the info necessary to visualize violence against real people.
Reason: Talking about such violence makes that violence more probable, and makes LW look bad; and numerous message boards across the Earth censor discussion of various subtypes of proposed criminal activity without anything bad happening to them.
More generally: Posts or comments advocating or 'asking about' violation of laws that are actually enforced against middle-class people (e.g., kidnapping, not anti-marijuana laws) may at the admins' option be censored on the grounds that it makes LW look bad and that anyone talking about a proposed crime on the Internet fails forever as a criminal (i.e., even if a proposed conspiratorial crime were in fact good, there would still be net negative expected utility from talking about it on the Internet; if it's a bad idea, promoting it conceptually by discussing it is also a bad idea; therefore and in full generality this is a low-value form of discussion).
This is not a poll, but I am asking in advance if anyone has non-obvious consequences they want to point out or policy considerations they would like to raise. In other words, the form of this discussion is not 'Do you like this?' - you probably have a different cost function from people who are held responsible for how LW looks as a whole - but rather, 'Are there any predictable consequences we didn't think of that you would like to point out, and possibly bet on with us if there's a good way to settle the bet?'
Yes, a post of this type was just recently made. I will not link to it, since this censorship policy implies that it will shortly be deleted, and reproducing the info necessary to say who was hypothetically targeted and why would be against the policy.
