Any engineer who is as smart as the SEO-gaming trolls spreading disinformation from the RNC or the St Petersburg "Factory", and can write search engine rules to undo theirs.

And the "plebs" would still "be allowed to hear and see" the fake news; un-gaming the Troll SEO will just put their dreck down on the eighth page of search results where it belongs, in stead of the first. (Well, "will"... Easily could, if it gets implemented that way. Which is all at least I would ask of the search engines.)
