Screenshots are not completely made up. At least the `usg` HMAC seems to be valid, and timestamps are recent enough, so the redirector URLs are legit. Of course it's possible to generate the valid redirector URLs in other ways.

So if this is a scam it's not a completely stupid scam.

Anyway, A/B testing or gradual deoployment is a thing. I'll not turn against a fellow hacker and call him shady, just because a potential A/B gaslighing practice from some megacorp. ;) I'll just wait.
