So what they're saying is that there are people uploading 60GB data of faces of the same person every month? How does snapchat not have the best face recognition algorithm by now? Even facebook doesn't have so many samples.
If you have ever used snapchat, they have these strange face-tracking filters, for example one of the most known is the "barf rainbows", where if it detects you've opened your mouth, it aligns rainbows coming out of it, and enlarges your eyes.
