Back in January I complained about how the reviews in BlackBerry AppWorld were beginning to be overrun with people posting their BBM pin rather than leaving useful reviews of the applications. At the time I proposed that RIM filter out reviews in the same manner that they filter out curse words.
In the past two weeks it has appeared that RIM has begun to do this. While some pin spam is still getting through, around 80% of the reviews that include a pin have been automatically denied. Hopefully this is enough that it will discourage the whole culture of trolling for BBM contacts in application reviews. Then when looking for new applications, users will have actually relevant reviews to look at instead.
