This would also leave intact cookies, local/session storage, indexeddb, caches. All of which abusers do actually check, when controlling their victims.
The thing that still works is the back button after the redirection to Google, and you can still un-close the tab with Ctr-Shf-T which pops the Google page with back history intact. They have "cache-control: max-age=0" which probably should be changed to "cache-control: no-store". Still, the back button has the history if the user clicked links. Improvements could be:
- Recommend the usage of incognito mode.
- Blank the page immediately with "document.body.innerHTML=''" before the page replacement, as the replacement alone can have a delay and the abuser could see a glimpse of the police page. Blanking is immediate.
That's what the "document.body.style.opacity = 0;" is for. Though I agree emptying out the body is probably better.
I am 100% sure that some do, thanks to firsthand life. And any doing it, is enough to get people dead, even if 99% don't. And yes, CS majors can be abusers, too.

Don’t underestimate an abuser’s ability to find a way.
