I'm always divided between liking that tools are available and thinking that it's pure ******** that they make things so easy. Of course, indirectly, they force security to improve, but still. Stuff like this, that targets one specific site, is like having a gun that can only fire when it's pointed, at, say, women 65 years old and up. Now, there MIGHT be legitimate use cases for it, but chances are, if you're getting it knowing what it does, you're interested in shooting old women due to some mental issue more so than having a tool for shooting things that might legitimately need to be shot. The same applies here. You might be interested in completely benign uses of the software. But unlike actual versatile tools, the overwhelming majority of users of something like this as going to be kiddies wanting to get some jollies of getting into people's facebook accounts. Not that there can't be good reasons for doing that - sometimes there can be - but that's not what most people will use it for, and everyone knows that.
