They don't even need to scrub it.
Just removing things from search results is enough to control the info.
I can't remember when it was, some time after the Covid lockdowns, but google deindexed results for 10,000 different websites in one year, mostly forums and blogs.
They've removed more since then, it's hard to find information outside of Wikipedia, Reddit, and tiktok/YouTube these days.
Duck duck go has been compromised, I don't even know what search engine to use anymore.
