Okay, the equivalent of a mustache on a stick and putting their microphone in a soup can for bass reverb.

And MindGeek are apparently claiming to be able to tell the difference between "age 17 and 11 months and 30 days" and "age 18" this way. Wow.

Although, given that much of the rest of their business existence also depends on the claim that there is a readily-visually-verifiable difference between those two ages, I suppose that's at least consistent.
