I'm not arguing that it's impossible to verify people: it's clearly not. The point is that it will end up being a painful and risky enough process that amateurs will respond by switching to other platforms hosted overseas, outside the reach of law enforcement. This will provide a space where the exact same problem as exists now--commingling of legitimate amateur porn and nonconsensual videos--reproduces itself, except with no tools available to expunge the videos that need to be expunged.

Every proactive approach has this downside. That's why we should focus more on making it easy for victims to report a video and have it and variations of it removed from all sites nearly immediately, as well as making sure laws are on the books making it easy to prosecute offenders.

What you’re arguing for can be classified under the “slippery slope fallacy”.

We have repeatedly seen that, while deplatforming does drive content creators to move to other platforms, these platforms will not have the same reach as the mainstream ones. I.e. it’s not a perfect remedy but it’s quite effective.
