"It surprises us that Mattel chose to direct Facebook to take down Scrabulous without waiting for to rule on the matter, Jayant Agarwalla, co-creator of Scrabulous, said in an e-mail.
"Mattel's action speaks volumes about their business practices and respect for the judiciary. It is even more astonishing that Facebook, which claims to be a fair and neutral party, took this step.''
Scrabulous has since been reworked into a similar game called Wordscraper, which looks to be sufficiently different from Scrabble to avoid court action.
At its peak Scrabulous had over half a million active users. Wordscraper currently has around quarter of a million, while Hasbro’s Scrabble application has over 370,000 users and Mattel’s non-US Scrabble has just over 70,000.
