The complaint contends that by doing so, Twitter breached its own terms and is asking the court to order Twitter to reinstate the doctors' accounts.

On May 12, Matthew Tyson, a lawyer representing the doctors, sent a letter (pdf) to Twitter requesting the reinstatement of five accounts: The three, plus Drs. Vladimir Zelenko and George Fareed.

In the letter, Tyson admitted that Twitter is a private company and reserves the right to suspend user accounts for "any or no reason."

"However, Twitter also implemented specific community standards to limit COVID-19 misinformation on the platform, and Twitter was bound to follow those terms," the letter notes.

According to its official 'COVID-19 misleading information policy," Twitter does not allow users to share "false or misleading information about COVID-19 which may lead to harm." That includes "false claims" that suggest that vaccines are not safe; promotion of "unapproved" and "potentially harmful" Covid treatments; and "false claims about COVID-19 that invoke a deliberate conspiracy by malicious and/or powerful forces," among others.
