I was working at the relevant domain registrar when the copyright complaint about Scrabulous came down (and the website went offline because the register had to break the connection between the domain name people typed in to get there and the server it was hosted on).

It was intense. We had to officially tell them that we knew nothing and they would need to contact the owner for more information.

Our shift whiteboard had a Scrabble "game" on it for a while after that.

Then Scrabulous rebranded to Words With Friends, and people got their game on again.
