Limitations with sharing duplicate content on Twitter

In an effort to control spam, Twitter has published its posting guidelines in February 2018 prohibiting the posting of duplicate content to multiple accounts. 

• Do not (and do not allow your users to) simultaneously post identical or substantially similar content to multiple accounts. For example, your service should not permit a user to select several accounts they control from which to publish a given Tweet.
• Do not (and do not allow your users to) simultaneously perform actions such as Likes, Retweets, or follows from multiple accounts. For example, your service should not permit a user to select several accounts they control to follow a specified account.

• The use of any form of automation (including scheduling) to post identical or substantially similar content, or to perform actions such as Likes or Retweets, across many accounts that have authorized your app (whether or not you created or directly control those accounts) is not permitted. For example, applications that coordinate activity across multiple accounts to simultaneously post Tweets with a specific hashtag (e.g. in an attempt to cause that topic to trend) are prohibited.Source: Twitter - Automation and the use of multiple accounts
  

Because of this policy, third-party social media management tools such as Vista Social cannot allow its users to post the same content to multiple Twitter accounts to ensure compliance. You are still able to schedule to multiple Twitter profiles -- just not the same message within 24 hours.
