> or uploading my face to a porn site.

I assume that in the pornography you've decided to consume, the participants are not clad in balaclavas.

They're showing their faces to everyone, in perpetuity, which many may no longer want to, and - considering the exploitative nature of the pornography industry, where rape is endemic - some didn't consent to in the first place.

So maybe consider that when you're complaining that your own face may be linked with pornography. Is what you're doing ethical? Do you reasonably have any right to complain?

Yes I do, and you argument is ridiculous. First of all, porn actors are operating legally and consent to what they are doing. There are real problems with the industry, but the fact that porn actors have their face shown does (of course) not mean that consumers of porn should logically have to also disclose theirs to online services.

Second, porn is just the beginning. This will also be rolled out to social media, and I wouldn't be surprised if in a few years this will be required in lots of places where children could be exposed to something that politicians find offensive.

What kind of argumentation is this? Just because someone decides to show stuff, everybody else is also required to show themselves? e.g. If I go to a theater where the actors are clearly identified, I have to be okay to get a facial scan as well?

Some people tend to demonize porn, and it might be unethical in their eyes, but fact is: it is not illegal (in most countries). I don't argue that there are issues in the porn industry, but this is an issue with the platforms, that they don't allow the upload of non-consentual material, or and have processes to take it down. This is a 'THEIR' problem (the platform not the victims).

There some of these issues also exist in the standard movie and music industry as well. Hell, it even goes up to company executives and politics. But this is up to law enforcement do their job and to remove the illegal stuff and prosecute the involved persons, not by branding everyone as a suspect.
