Upload your fake text and images anywhere. Upload it everywhere. Upload it as yourself. Upload it on behest of your willing friends. Corrupt your face in dozens of ways, then tag each as yourself. When everything is garbage, shadow profiles will mean nothing, social credit scores will mean nothing, analytics will mean nothing.

What's extremely frustrating is that the only alternative I've ever seen proposed are forms of a never-ending moderation arms race, some variant of a "war on fakes". Which is even scarier in the long run, because while it mitigates the damages here and now (good), it would never solve the underlying problem, and only further cement some parts of it (enforced trust invites potential abuse).
And as usual, humanity is currently stuck between two incredibly shitty options (traditionally going through a path of least resistance, no matter what could be at the end of it - because that's how large systems work), hopefully still searching for a magical third silver bullet.
