Sorry but that's just baseless scaremongering and it is completely irrelevant whether someone knows about their server or not. The "resouces" used by search and replace are so small I doubt you could actually measure them - and your server would already need to be on the edge of imminent collapse for them to ever cause a problem - in which case you are already in big trouble anyway.
