The singer-songwriter's track 'Last Night' had soared up the download chart this week after appearing on Saturday's edition of the show.
However, her self-released LP Top Room at the Zoo has now been deleted from the music service due to an apparent X Factor rule change.
Spraggan was told to take down her album and informed that all other X Factor contestants this year have also been banned until the show is over, in order to give them the same level of exposure, reports The Sun.
"Oh dear - not my call to make. Get it while you can," Spraggan wrote to her fans.
"I've obliged because you've got to do what you've got to do to get somewhere in life."
'Last Night' had reached as high as number two on iTunes earlier this week, behind only last year's X Factor winners Little Mix.
Spraggan may still reach this week's singles chart, with the midweek chart update to be revealed later today (August 29).
