Twitter is temporarily limiting the accounts of users that exhibit bad behavior for up to 12 hours.

Several users have uploaded screenshots of warning messages from Twitter if Twitter detects behavior that violates their rules.

Twitter says they will temporarily limit certain account features, like the ability for your tweets to be seen by people outside of your followers. Upon receiving the warning message, users are able to activate a 12-hour countdown until they can begin using Twitter normally again.

Twitter announced last week that it would be adding new features to curb online abuse.

Why it matters: Some users see Twitter's crackdown as a violation of free speech. But tech giants are all facing similar predicaments. Snapchat recently announced updates to its publisher guidelines to filter sensitive material and Facebook has been under pressure for private and public officials to crack down on hate speech.

President Trump's final debate performance exceeded Americans' expectations, but it wasn't enough to shift the dynamics that left him trailing Joe Biden across most measures, according to a new Axios-SurveyMonkey poll.

What they're saying: "Liar" was the word used most by debate watchers to describe Trump's performance, followed by "lies," "strong," "presidential" and "childish." "Presidential" was the word used most to describe Biden's performance, followed by "liar," "weak," "expected" and "honest."

The mainstream media turned away. But online, President Trump's charges about Hunter Biden were by far the dominant storyline about the final presidential debate, according to exclusive NewsWhip data provided to Axios.

  • Coverage of business dealings by Joe Biden's son — and pre-debate allegations by one of his former business associates, Tony Bobulinski — garnered more than twice as much online activity (likes, comments, shares) as the runner-up.

From high levels of obesity and opioid addiction to inequities in access to care, America's pre-existing conditions make the country an easy target for COVID-19, as well as future pandemics that could cripple the United States for decades to come.

Why it matters: One of the best ways the country could prepare for future threats — and boost its economy — is to improve Americans' overall health.
