I found a different pic which had 2 words watermarked on it, petitelexxx and icanbeurnuocmami.
petitelexxx led nowhere, but icanbeurnuocmami led to a reddit page, which led to a Twitter with the name, Nuoc Mami (links below).
I then found another pic with another name, also leading nowhere (petitlex12 or petitelex 12).
Anyhow, I'll upload the last pic and maybe someone else can figure this out. Is the "Nuoc" girl the one on her knees, or the other girl?
