Pinterest and Twitter are very proactive in marking duplicate content as spam. They have given certain guidelines over sharing similar content. Due to this, Social Champ has put certain limitations when it comes to posting similar content.
They have advised third-party apps and users to follow certain guidelines in their respective Twitter automation rules and Pinterest Community guidelines.
”Multiple posts/accounts: You may not post duplicative or substantially similar Tweets on one account or over multiple accounts you operate”- Twitter
”Don’t create or save content that is repetitive, deceptive, or irrelevant in an attempt to make money. To learn how to make great Pins, you can always refer to our creative best practices”- Pinterest
In light of the above guidelines from Twitter and Pinterest, Social Champ doesn’t allow posting the same/similar content to prevent spamming on both the platforms.
We do think that the above measures that Twitter and Pinterest took to avoid the same content were pretty much needed to provide users with authentic content only.
