Best Answer
Facebook apps no longer have profile pages, although the developer has the option of creating a page linked to the app. Since that is the page containing the option to block the app and it is now optional, there may not be a way to block the app from the Facebook interface any more for these apps. That does seem like an issue for Facebook to address. However, in the mean time it can still be done from a script. A search found this userscript which adds a Block link to the bottom of the authorization dialog (before Report App), allowing you to block the app from there. I tried it on the BWS app and successfully blocked it.
