YouTube's move of banning content by the U.S. conspiracy theorist Alex Jones comes days after Facebook, Apple and Spotify toughened their stand against the radio show host and banned him on their platforms.
As BuzzFeed's Charlie Warzel pointed out, Jones does use Twitter differently from the way he uses other social-media sites, posting less inflammatory content. Dorsey's announcement after Apple, Facebook and YouTube earlier this week removed some content from Jones and InfoWars.
"We didn't suspend Alex Jones or Infowars yesterday", he wrote.

He said he wanted the company to avoid succumbing to outside pressure but instead impartially enforce straightforward principles "regardless of political viewpoints". The four companies stated that Jones' disparaging comments about Muslims, immigrants, members of the LGBT community, and several other groups of people violate the hate speech clauses in their respective terms-of-service agreements.
Spotify, the streaming music online service, had already removed a number of Jones's podcasts last week, accusing them of breaking its own hate-speech rules. A separate Twitter account for Infowars is also still running. Twitter has recently stepped up actions against fake accounts, but the company has admitted that it has no "scalable policy or set of product features around authenticity of content".
Dorsey also said in his tweet thread that it is the responsibility of journalists to "document, validate, and refute" the information that "accounts like Jones'" often spread.
Among the conspiracy theories Jones has peddled are charges that the USA government was behind numerous terrorist attacks, including the September 11, 2001 strikes on the World Trade Center and the Pentagon.
Dorsey appeared to take a swipe at the tech platforms that banned Jones and said Twitter refused to take "one-off actions to make us feel good" or make decisions that could ultimately fuel "new conspiracy theories".
