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.

Congress' next moves to rein in Big Tech

After grilling the CEOs of Amazon, Facebook, Google and Apple last week, members of Congress are grappling with whether to accuse any of the firms of illegal anticompetitive behavior, to propose updating federal antitrust laws — or both.

The big picture: Congress is just one arm of government making the case against these companies. Google is expected to be the first of the firms to face possible antitrust litigation from the Justice Department before summer's end, but all four face a full-court press of investigations by DOJ, the Federal Trade Commission and state attorneys general.

Fauci: Coronavirus task force to examine aerosolized spread

The White House coronavirus task force will examine more closely just how much SARS-CoV-2 might be transmitted via aerosols, and not just from droplets, NIAID director Anthony Fauci said Wednesday at an online forum sponsored by Harvard T.H. Chan School of Public Health.

Why it matters: The longer the coronavirus can remain infectious in the air, the more likely it can infect people, particularly indoors — leading to the possible need to alter air filtration and circulation within buildings.

The next wave to hit Main Street

Call it the great retail wash. A wave of defaults, bankruptcies and evictions expected in cities across the U.S. is poised to remake the retail landscape across the country, but there may be some upside for consumers and small businesses.

Why it matters: Rather than an overnight descent into a collection of urban wastelands full of Starbucks, Amazon fulfillment centers, Chase bank branches and nothing else, the coronavirus pandemic and resulting retail apocalypse may just mean that, in major U.S. cities, less is more.
