Probably one of those studies on "what people are up to, when they use Tor".

Two that I know of (in Russian):
http://habrahabr.ru/post/92787/ and
http://habrahabr.ru/company/xakep/blog/244485/

Also keep in mind those absolutely don't have to be public, there could be
much more sniffing and crawling going on than we could imagine. Does not
seem too evil however, and I'd say that's not a reason to ban exit nodes.
