Participating in Twitter trends is a great way to join a worldwide public conversation. Our FAQs about trends on Twitter article has information on how to join in. However, posting unrelated Tweets to trends in order to get attention could result in your account being suspended.
While Tweets promoted through Twitter's advertising services are labeled as “Promoted” and must abide by our Twitter Ads Policies, organic, non-promoted Tweets may also be considered paid product placements, endorsements, or advertisements (“‘Paid Partnerships”). Please see our Paid Partnerships policy for details.
Search (and contests)
Twitter search is a powerful way to find out what people are talking about, right now. We may filter accounts from search if they're degrading the search experience for other people (by posting lots of duplicate links, for example). Read about our Twitter search rules and restrictions for more information. To learn how to run a contest, read about our Guidelines for Promotions on Twitter.
