In February 2018, Twitter introduced new guidelines to prevent the misuse of multiple Twitter accounts to artificially amplify a message. Twitter has defined spam in its Twitter Rules and Automation Rules, and has urged third-party apps and all users to be mindful of two specific policies:
"Using multiple accounts you control to post duplicative or substantially similar content, replies, or mentions, or creating duplicate or substantially similar accounts, with or without the use of automation, is strictly prohibited. Posting multiple updates on a trending or popular topic (such as a specific hashtag) with the intent to manipulate or subvert the topic, or to artificially inflate the prominence of a hashtag or topic, is also not allowed."
As a result, third-party services, such as Ocoya, are not permitted to enable users to share the same post to Twitter, either on multiple Twitter accounts or multiple times on one account.
Therefore, Ocoya users will receive an error when attempting to post duplicate content on Twitter. You can still schedule content to multiple Twitter accounts using one Ocoya account, but you cannot use the same message.
