No, no, no. ToysRUs made a perfectly logical decison that most any business would do and Google tanked them for it. ToysRUs wanted the url toys.com to direct to their site. They're all about toys and they simply bought a url that described their business and told the url where to take people. Google tanked them in the rankings because Toys.com came with link juice. Google assumed that Toys.com was doing this to manipulate the search engines but there is just, to my knowledge, ZERO evidence of this. This is another case of Google caring more about the possible spam threat than the actual rankings for searchers.

There’s an important distinction to make here between domain flipping and website flipping. The latter mainly refers to buying and selling full websites. By full websites, I mean websites that actually have content and more often than not have traffic and revenue. When buying and selling websites, the domain name matters less as the main value there is the content, traffic, revenue, history/reputation, sustainability and growth opportunities. The same can’t be said for domain names where you’re just selling “the name” and hence it’s all that really matters.
