Timely given I just tried to sign into Meta for the first time in a year or two as I am being required to work on a Marketing API integration, got prompted for a video selfie(!) and my account is now in "Community Review" as maybe my expression was too grumpy about being required to present myself for inspection. Abhorrent company.
