MOODY v. NETCHOICE, LLC 

ALITO, J., concurring in judgment 

violent, obscene, sexually explicit, and false posts that vio-
late their community guidelines.  Brief for Developers Alli-
ance et al. as Amici Curiae 11.  Some platforms—like X, for
instance—say  they  use  algorithms,  not  for  the  purpose  of
removing all nonconforming speech, but to “promot[e] coun-
terspeech” that “presents facts to correct misstatements” or
“denounces  hateful  or  dangerous  speech.”47   Still  others, 
like Parler,48 Reddit,49 and Signal Messenger,50 say they en-
gage in little or no content moderation.

Some  platforms  have  also  disclosed  that  they  use  algo-
rithms to help their users find relevant content.  The e-com-
merce platform Etsy, for instance, uses an algorithm that 
matches  a  user’s  search  terms  to  the  “attributes”  that  a 
seller ascribes to its wares.51  Etsy’s algorithm also accounts
for things like the date of the seller’s listing, the proximity
of the seller and buyer, and the quality of the seller’s cus-
tomer-service ratings.  Ibid. 

YouTube says it answers search queries based on “rele-
vance, engagement and quality”—taking into account how 
well a search query matches a video title, the kinds of vid-
eos a particular user viewed in the past, and each creator’s 
“expertise,  authoritativeness,  and  trustworthiness  on  a 
given topic.”52
