How would SE change it? I mean they can ban people. Those are against ToS. There may be some places they can shore up things on their side a bit. But they don't know what we have installed on our PC and Yoshi-P has said in more than one interview that he doesn't want to go down the path of invasive sniffing programs.

I think it's a crappy situation but I imagine SE is limited on what they can really do without hurting a lot more innocent people.
