Twitter wants researchers always to pull fresh data. It is because a user might delete a tweet or make their profile protected. If the same tweet has already been pulled and shared on a public domain, it might make the user/community vulnerable to many inferences coming out of the shared data which currently does not exist or is private.Do you have tweets collected before March 20, 2020?Unfortunately, I had to unpublish more than 20 million tweets collected between Jan 27, 2020, and March 20, 2020, because the collection did not have tweet IDs obtained. "Why?" you might ask. Initially, the primary objective of the deployed model was not just to collect the tweets; it was more like an optimization project aiming to study how much information, received in a near-real-time scenario, can be processed with minimal computing resources at hand. However, when the COVID-19 outbreak started becoming a global emergency, I decided to release the collected tweets rather than just keeping them with me. But, the collection did not have tweet IDs. Which is why a fresh collection was started after March 20, 2020.
