Trump was likely trigged by coverage around a viral article from VICE News, which asserted Trump Jr.'s spokesperson and RNC Chair Ronna McDaniel had been "shadow banned" from the platform.

What's happening: People need to start by understanding that this is all about auto-fill in the search box, Axios tech editor Scott Rosenberg says.

• "Shadow banning" is as badly misleading a phrase as the "Hillary Clinton acid washed her server" line (all based on the name of a software utility called "bleachbit").
• Algorithms have played a role in deciding who sees what and when since Twitter went away from a purely chronological timeline.
• Everyone is either shadow lifted or shadow demoted (no one is really being fully shadow banned).

Reality check: New York Magazine's Brian Feldman reported that Twitter's technique is similar to something Facebook has done previously.

• Facebook's best attempt to "dispel information from places like InfoWars...was to secretly minimize their distribution in the site's News Feed."

What Twitter's saying: "To be clear, our behavioral ranking doesn't make judgments based on political views or the substance of Tweets."

• The other side, as the original Vice article noted: "Democratic Party chair Tom Perez, and liberal members of Congress ... all [continued] to appear in drop-down search results. Not a single member of the 78-person Progressive Caucus [faced] the same situation in Twitter’s search."

The bottom line: Among Americans, 72% believe social media intentionally censors political viewpoints they find “objectionable.”

• That includes 62% of Democrats and a whopping 86% of Republicans.

What's next: Twitter, whose shares fell nearly 3% today, reports earnings tomorrow.
