Social media posts may be used as long as they meet the requirements for digital source material: the posts may not be written by the performer and the posts must be publicly accessible for the duration of the tournament. To be publicly accessible, the posts must not be password protected, so make sure the account of the poster is public and does not require someone to log in to the site. Additionally, check to ensure the posts are still online during competition. Posts that were public at one time but became deleted or private by the time you are competing, those posts are no longer acceptable to use.
