Don't the XF 'Powers That Be' regularly erase the musical pasts of contestants? I'm pretty sure that it keeps cropping up every year how a contestant has previous 'form' as a singer, which was erased from the internet as soon as they got through to the lives. Basically, TPTB want us to believe that everyone on the live shows has never performed in public before, had a recording contract or made/released a record.
They want the viewers at home to believe anyone can walk in off the street and become a pop star, when the truth is that many of the contestants will have some kind of performing experience (be it pubs/clubs, holiday camps, cruise ships, musical theatre or in the pop industry).
