我替懒人们把推特的这个 Policy 拷贝过来了， 看看吧
What is in violation of this policy?
Under this policy, you can’t state an intention to inflict violence on a specific person or group of people. We define intent to include statements like “I will”, “I’m going to”, or “I plan to”, as well as conditional statements like “If you do X, I will”. Violations of this policy include, but are not limited to:
threatening to kill someone;
threatening to sexually assault someone;
threatening to seriously hurt someone and/or commit a other violent act that could lead to someone’s death or serious physical injury; and
asking for or offering a financial reward in exchange for inflicting violence on a specific person or group of people.
What is not a violation of this policy?
We recognize that some people use violent language as part of hyperbolic speech or between friends, so we also allow some forms of violent speech where it’s clear that there is no abusive or violent intent, e.g., “I’ll kill you for sending me that plot spoiler!”.
This policy is enforced in tandem with our policies on abusive behavior and hateful conduct. Statements that express a wish or hope that someone experiences physical harm, making vague or indirect threats, or threatening actions that are unlikely to cause serious or lasting injury are not actionable under this policy, but may be reviewed and actioned under those policies. Note: we also have a policy against encouraging self-harm and suicide.
这个文章中说的例子，可以归到推特认为不需要被删的，没有构成现实威胁的言论:
We recognize that some people use violent language as part of hyperbolic speech or between friends, so we also allow some forms of violent speech where it’s clear that there is no abusive or violent intent, e.g., “I’ll kill you for sending me that plot spoiler!”.
当然这个判定有一些主观性, 但是确实如果类似这样的话要删，估计推特得整天忙着删不停了。
文学城版主们明显就比推特都更大主观性, 更大权力自己决定删谁不删谁，删什么不删什么; 主要就是无需写出明确的规则，沿用一条中国式的"正能量"要求，就能给管理者很大的空间。
“民主”、“自由”只是攻击他国的工具，驰名双标的美国最会演戏，世界上有明白人，不像中国那些读书读傻的呆子，对西方说教深信不疑，成了无脑的牵线木偶。
黎巴嫩外交官推特：
If the United States saw what the United States is doing in the United States, the United States would invade the United States to liberate the United States from the tyranny of the United States
如果美国看到美国正在对美国做的事情，美国一定会入侵美国，并从美国暴政下解放美国。

美国密苏里州共和党籍参议员霍利（Josh Hawley）在参议院率先请缨挑战总统大选选举人票结果，成为美国一些自由派人士的眼中钉，不但新书被出版社取消出版，还被家乡报章挞伐，更有学者在“推特”公然发文恐吓，称霍利应该被“活生生剥皮”。
据美国保守派杂志《国家评论》9日报道，美国国家卫生研究院（NIH）前高级政策分析师吉特林（Jonathan Gitlin）多次在推特口出狂言，称霍利胆敢挑战2020年大选的公正性，应该被“活生生剥皮并扔进盐桶里”（ to be skinned alive and rolled in salt）。
虽然吉特林后来删除这则推文，但1月7日，在支持川普的“停止窃取（Stop the Steal）”集会游行后的翌日，吉特林回应一条责备霍利挑战选举舞弊的推文时，又再发出次同样威胁，并强调，他坚持之前删除的那条推文，认为霍利确实应该被活剥皮，然后扔进盐桶里。
吉特林曾是肯塔基大学的兼职教授，现任科技新闻网站Ars Technica的汽车编辑，2009年至2015年，他曾NIH工作了6年多。NIH是美国防疫专家佛奇所属全国过敏和传染病研究所（NIAID）的上级单位。
《国家评论》质疑，在吉特林任职期间，佛奇是NIAID的掌舵人，可能因佛奇的推荐，NIH才僱用吉特林担任高级职位。
佛奇美国大选前就被川普支持者质疑行政不中立，在受访时将防疫政治化，身为防疫小组成员不向总统提政策还到处放话，甚至称赞拜登的防疫政策。
