Too bad that things move this fast and neither I nor @CyberGene had time to try the instruments.
I did not miss the fact that our own CG lives in a city called Sofia, and that @Sofia_MZ spoke a slightly too good English (and with the right British accent which the very rare native-Italian good-English speakers have, which I often exploit for embarrassing them when I speak about my pants, having them misunderstanding those for underpants, but I digress....)
She also spoke great Roman slang, even if it had slight grammatical mispells (it's "sdrumata" not "sdrumada" as she wrote), but all of them were reasonable mistakes that some real native speakers make.
So in the end, I definitely fell in the trap, despite my thought of "holy crap, what a pedigree of instruments can she access and sample!" -- also the names of the instruments, their locations, everything very credible even for somebody who lived (or visited relatives) in many of those places! Congratulations!!!
Everything seems very carefully done, including preventing archive.org from crawling https://luciphercode.wixsite.com/sofia-mz so that now https://web.archive.org/web/20230000000000*/https://luciphercode.wixsite.com/sofia-mz is a 404 and the website is really gone for real.
Very interesting to watch this unfold (in accelerated motion since I typically don't have time follow the forum on business days).
@CyberGene can you rename the thread? The title respects only the first message or perhaps two, and everything else should be instead titled "Debunked!" -- I think it's okay to leave the thread as is (no need to split, IMHO) but do change the title please?
