Congolese (and Francophone Artists) use SNEP for certification, which is National Syndicate of Phonographic Publishing. Interestingly, world artists are not listed on their site, but their representatives are the ones who distribute gold/platinum disc to artists who meet sales requirements
American (and Anglophone artists) use the RIAA, the Recording Industry Association of America for certification
To answer your question, like many online who have investigated - there's no legitimate way Fabro could've gotten two separate disc d'ors that quickly when way less than 50,000 CDs were fabricated. Streaming, supposedly, still has a small impact on SNEP requirements. Only RIAA made changes to make streaming equal to CD sales, which is why it seems like American artists got platinum every week.
Lastly, the encasing of Fabro disc d'or is way nicer that even what platinum selling American artists receive; so it's very suspect.
