The exact same thing happened to me recently, and yet I had some activity, though not much. And there was absolutely no content in my account that could be construed as violating any terms of use. I posted pictures like once or twice a year.

Suddenly my account was disabled, with instructions to send an image of myself holding up some code; but nothing has happened since I sent it.

I wonder if any due diligence is done on approximating good user impact from a hypothetical like this, or if they would just YOLO it.
