Open redirectors are, of course, very bad in general, but the largest
"Internet properties" have whole business models absed on them (and
thus on helping the fraudsters and scammers), so WTF should anyone else
care about them??

For those looking for malice, this one can be simplified to:

http://profile.myspace.com/index.cfm?fuseaction=cms.goto&_u=[...]

(where "[...]" is the target URI).

And, of course, you can further obfuscate it by stuffing it with bogus
parameters.

Yet further obfuscation possibilities with escaping and so on are left
as an exercise for the reader...
