Thank you for your inquiry. I would like to clarify that the event was held from December 24 to January 6, and all winning users have been selected strictly based on their valid participation during this official period. Their rewards were granted for completing the required steps—specifically, changing both their profile frame and avatar (along with any retweet requirements, if applicable)—within the designated timeframe. Please note that the requirements regarding profile and retweet actions were applicable only during the event period. After the event concludes, users are free to change back to any profile picture they prefer. The selection process is fair and fully in accordance with the published event rules. We appreciate your understanding and continued interest in our activities. And always welcome your participation in future events💙
