After 2 years of users complaining about Twitter Shadow Banning, and Twitter denying that it's happening the company finally admits that it was happening and blames it on a bug.
This so-called bug was quickly fixed after Trump tweeted about it.
And then Twitter stock fell 20% for their shenognigans
Twitter appears to have relaxed the effects of its “quality” search filter function associated with so-called “shadow banning,” after evidence indicated that the content of some accounts on the social media platform was obscured to followers, while many others appeared to be unaffected.
The Epoch Times discovered the change in the filter functionality while researching the shadow banning phenomenon. Some search results changed overnight on July 28 after The Epoch Times alerted Twitter to some of its findings.
On July 26, President Donald Trump addressed shadow banning, which appeared to affect certain Republicans, and promised to “look into this discriminatory and illegal practice at once.” On July 27, Rep. Matt Gaetz (R-Fla.), whose Twitter account was affected, said he filed a complaint against the company with the Federal Election Commission (FEC).
For several years, Twitter users have accused the company of shadow banning—hiding a user’s content from other users without informing them.
While the full extent and history of the practice remain unclear, one identified method was to remove the tweets of targeted accounts from search results, unless a user turned off the “quality” filter function, found in the “search filters” box. The filter is on by default and snaps back on after just one search.
