X OPEN SOURCES ITS RANKING ALGORITHM, LETTING USERS SEE IF THEY'VE BEEN ‘SHADOWBANNED'

Summary from the TLDR newsletter

X has open-sourced its 'For You' algorithm and its core ranking engine under the Apache v2 license. The company has also expanded its previous efforts to open source parts of its codebase to add more detail, making it roughly 10 to 15 times larger than it was before. X is providing tools that will let users see for themselves if and how its ranking systems have impacted their account or posts. The tool will be available to a test group of accounts for at least a year as a pilot before rolling out more broadly.
