Bing copying Google search results

The TL;DR version of the above story is that Google were suspicious that Bing was returning very similar results for a lot of searches. They did some investigation along with some intentional traps and found that Bing was copying their results.

Google claim that they made a one time only tool that intentionally put some fake data into their results and this was the first and only time this has ever happen. Mhm... Sure...

It seems that the Bing toolbar and the IE search suggestion feature monitors what you're doing and sends it to Microsoft. Its listed that this happens so they're not doing it secretly but this is the first time I've seen it actually have any real world visible result. I assume Google/Yahoo and everybody else who has a search engine + toolbar does exactly the same thing so this isn't singling Microsoft/Bing/IE out for anything.
