However they do allow the tweet IDs to be shared. You can use this data in combination with their data API to "hydrate" the IDs to get the original data. A tool like twarc can be used to hydrate them automatically.Note: We did not seek consent from the thousands of users who posted their public content on the Web. If you do hydrate the dataset and use it in your research we do ask that you consider their rights as content creators, especially with regard to their privacy.
