Oh, the irony. Swedish tea brand Kobbs launched a competition in which consumers were challenged to stay off of Facebook for a week. To take part in the competition, users had to connect via their Facebook profile. The competition was supposed to last for a month, but was closed down today, after being live only for a few days.
There is no publicly available information explaining why Facebook shut down the contest. My guess is that there could be several reasons that the contest was in breach of Facebook Promotions Guidelines, but the use of the brand Facebook in the contest headline is a prime suspect.
