I always aim right for the heart, @DIDIx13**. ;)
But yeah, the “social” part kind of requires that you make other people do stuff, as the definition that @sorrox posted also shows. I don’t see how just requesting a new password on a site comes even close to that, but perhaps I misunderstood what you meant.
It seems to me to just be some information disclosure that you’d exploit. I doubt any big site does this, though. Then again, they’ve been known to do stupid things…
