Remember when they proved that bing was just providing google search results?
Like it straight up sent your search query to google search and fed back the results in the bing skin.
Edit: i am uncertain that this is true, after a search i found this article from 2011
This is what i was referring to. I explicitly remember reading this story, either on bbc or somewhere else, back then but i didnt look into it any further at the time.
I have had a quick look around (im in work) and there is a possibility that it was never proven. But i dont have a reliable source to show that at the moment. If anyone wants to fact check, be my guest. But please dont, as another poser did downvote my comment and post images of a google and bing search you did just now as evidence that my claim is false without looking into the validity of my claim.
The link above is from 2011, as i said, and shows what i was claiming.
Found this out in school when someone wrote some less than acceptable words on the board in permanent marker. The teacher scribbled over it with drywipes, waited a few seconds and wiped it away.
They said it was because essentially drywipe marker is a permanent marker with solvents.
