They never went after their fans. That's the hypothetical scenarios most people were afraid of. They had one angry twit against Ellen, they had some weird take down (which didn't need theses trademarks either).

All I've seen them trying is to allow people to legitimately do a copy of their show. I wouldn't never try to copy that format, I wouldn't be afraid to make my own "react to" but I would try to be different, original, with the concept. Having access to their format, their contents, etc... that could be a good way to try, to start, a way that I wouldn't dare taking because of copyright, but would be interesting for simply 20% of literally not much revenue.

Stopping React World does nothing else than stopping legitimate copy...
