Imagewind was a nifty little WP7 app that pulled in images randomly off Twitter for your enjoyment, and even though it was up for download for two weeks, Microsoft has just killed it. Why did this happen? Since it randomly downloads images, there’s the potential for mature content to come through, something MS wanted filtered out, but isn’t possible. So they unpublished it:
Imagewind – app unpublish request
[..] While the images shown are dynamic, per your app’s disclaimer, a portion of the images’ content is too graphic for the app to be permissible in Marketplace. In order to be permissible, there would need to be a content filter before surfacing images since users are not querying a specific type of image and are rather pushed to them.
Given this, we ask that you unpublish your app within one business day until you are able to modify your application to comply with the certification guidelines.[..]
Thank you for your understanding in the matter, and we will hope to see an updated version soon.

Because there’s no way for the app to filter out the inappropriate content, it’s going to get “unpublished.” Welcome to the world of the curated app store. This sort of thing is bound to happen, as people get a feel for what is and isn’t allowed by Microsoft.
