Twitter’s revised “Private information and media policy” now forbids users from sharing “live location information, including information shared on Twitter directly or links to 3rd-party URL(s) of travel routes, actual physical location, or other identifying information that would reveal a person’s location, regardless if this information is publicly available.”

An Internet Archive snapshot shows the rule was not present the day before Sweeney and @elonjet were banned.
