Therefore, the statement "the universal accreditation agency for online education is fake" is itself inaccurate. There is no such universal agency, so the question of its fakery is moot.
To determine the legitimacy of an online program's accreditation, you must investigate the specific accrediting agency they claim to have. Research the agency independently to verify its recognition and standards. Look for information on its website, and check with your national or regional government's education department (for example, the Department of Education in the US, or equivalent bodies in other countries) for a list of recognized accreditors.
