it takes 5 minutes or so for twitter to determine if they are going to ghost your tweet. what do they use to determine? 1, i guess an identical photo is automatic ghost? identical to a photo that has been used in the same account. what if its identical to a photo used in other accounts? 2, will they ghost your account? (e.g., if too many of your tweets are ghosted) 3, i am tempting to conclude that too many tags, or use of trending tags will not cause ghosting 4, i couldnt figure out why a 'dramatically' different tweet gets ghosted. do they have memory of deleted tweets?
