I think the student can lose. If there are thousands of diplomas in the market, employers might just think that they are not worth the paper regardless of accreditation. Some people expressed that they want to do 10 Masters from this school, imagine the perception of an employer with a CV with 10 masters from ENEB. I received an offer to upgrade my certificate to a Master for 160 USD, I was tempted but quite honest I dont think it would help me much. I would be cautious about filling your CV with cheap Masters degree from the same school.
