Spam, powered by Yahoo!

I received an otherwise uninteresting spam email today, with an interesting link:*-****.net/home.asp (I have ****'ed out the final domain name to avoid giving them any additional advertising).

The above is a fully valid url - ending up at Yahoo!. Yahoo then is kind enough to redirect the unfortunate user to the spammer's site:****.net/home.asp

Yahoo actually allows this without any questions. Try*- for example. Or*-

As best I can tell, Yahoo uses this service to redirect (and track) clicks on ads, etc. They have another service that does the same:, but at least it's smart enough to check the final destination:*- (or maybe it just uses a different scheme).
