If there's a photo of you anywhere on The-Platform-Formerly-Known-As-Twitter, then that's it. That's biometric data.
People have this weird idea that "biometric data" needs some special scanning process like in movies. As if some green laser needs to sweep across your body to "collect" biometric data.
A photo is all that's needed. That's it.
You read these articles that talk about "the dangers of biometrics" (in the context of facial recognition) and they often cite that the database can be hacked and people's biometric data will get stolen.
That's not a concern. Every system that captures biometric data for later use is completely different than the next system. It would be like trying to run an Android app on an iPhone.
Actually, it's very much like the pre-IBM days. There were many different computer systems that weren't compatible with each other. Biometrics is like that, but 100 times more incompatible. Each system needs a ground truth photo to generate the model/template/biometric data.
So I'll say it again, if there's a photo of you on Former-Twitter, even a profile photo, they have your biometrics.
