According to “The Twitter Rules,” posted on the Twitter website:

We believe in freedom of expression and open dialogue, but that means little as an underlying philosophy if voices are silenced because people are afraid to speak up.

In order to ensure that people feel safe expressing diverse opinions and beliefs, we prohibit behavior that crosses the line into abuse, including behavior that harasses, intimidates, or uses fear to silence another user’s voice.

Context matters when evaluating for abusive behavior and determining appropriate enforcement actions. Factors we may take into consideration include, but are not limited to whether:

• the behavior is targeted at an individual or group of people;
• the report has been filed by the target of the abuse or a bystander;
• the behavior is newsworthy and in the legitimate public interest.

Abuse: You may not engage in the targeted harassment of someone, or incite other people to do so. We consider abusive behavior an attempt to harass, intimidate, or silence someone else’s voice.

Unwanted sexual advances: You may not direct abuse at someone by sending unwanted sexual content, objectifying them in a sexually explicit manner, or otherwise engaging in sexual misconduct.

Hateful conduct: You may not promote violence against, threaten, or harass other people on the basis of race, ethnicity, national origin, sexual orientation, gender, gender identity, religious affiliation, age, disability, or serious disease. Read more about our hateful conduct policy.

Hateful imagery and display names: You may not use hateful images or symbols in your profile image or profile header. You also may not use your username, display name, or profile bio to engage in abusive behavior, such as targeted harassment or expressing hate towards a person, group, or protected category. We will begin enforcing this rule on December 18, 2017.

So much for the official version of what Twitter users—and non-Twitter users—can expect from those charged with policing Twitter.

Which leads to the question: Why hasn’t Twitter policed—and purged—the single greatest abuser of its “Twitter Rules”: Donald Trump?

Consider:

Donald Trump’s tweet-first-and-never-mind-the-consequences approach to life has been thoroughly documented.

From June 15, 2015, when he launched his Presidential campaign, until October 24, 2016, he fired nearly 4,000 angry, insulting tweets at 281 people and institutions. The New York Times needed two full pages of its print edition to showcase them.

Among these targets were:

• His Democratic rival, Hillary Clinton
• His fellow Republican Presidential candidates
• Actress Meryl Streep
• News organizations
• President Barack Obama
• Comedian John Oliver
• Obamacare
• Singer Neil Young
• The state of New Jersey
• Actor Arnold Schwarzenegger.

His Twitter assaults have often dominated entire news cycles for days on end.

As President-elect, he continued these assaults—such as the one on November 18, 2016.

On that evening, Vice President-elect Mike Pence attended a Broadway performance of the hit musical “Hamilton.”

After the curtain call, the actor Brandon Victor Dixon—who plays Aaron Burr—respectfully addressed Pence:

“We are the diverse America who are alarmed and anxious that your new administration will not protect us, our friends, our children, our parents, or defend us and uphold our inalienable rights. But we truly hope that this show has inspired you to uphold our American values and to work on behalf of all of us.”

Dixon—who is black—was rightly alarmed.

Trump had received the open and enthusiastic support of the Ku Klux Klan, American Nazi Party and other white supremacist groups. Since his election, white thugs had assaulted blacks and other non-whites across the country.

Trump’s reaction to Dixon’s plea came in two Twitter rants:

“Our wonderful future V.P. Mike Pence was harassed last night at the theater by the cast of Hamilton, cameras blazing. This should not happen!”

And: “The Theater must always be a safe and special place. The cast of Hamilton was very rude last night to a very good man, Mike Pence. Apologize!”

And during his first two weeks as President, Trump attacked 22 people, places and things on his @realDonaldTrump account.

Then, on March 4, 2017, in a series of unhinged tweets, Trump accused former President Barack Obama of tapping his Trump Tower phones prior to the election:

“Terrible! Just found out that Obama had my ‘wires tapped’ in Trump Tower just before the victory. Nothing found. This is McCarthyism!”

“Is it legal for a sitting President to be ‘wire tapping’ a race for president prior to an election? Turned down by court earlier. A NEW LOW!”

“I’d bet a good lawyer could make a great case out of the fact that President Obama was tapping my phones in October, just prior to Election!”

“How low has President Obama gone to tapp my phones during the very sacred election process. This is Nixon/Watergate. Bad (or sick) guy!”

Thus, without offering a shred of evidence to back it up, Trump accused his predecessor—on Twitter—of committing an impeachable offense.

On May 9, 2017, Trump abruptly fired FBI Director James Comey.

Reports soon surfaced that his reason for doing so was that Comey had refused to pledge his personal loyalty to Trump.

Trump had made this “request” during a private dinner at the White House in January. 

Another unpunished violation of Twitter’s Terms-of-Service was about to occur.
