The point of telling people to search for their particular fandom and RPS through a search engine is that we're all supposed to be paranoid about The Powers That Be finding our fic, and such a search is supposed to prove just how easy it would be. However, that suggests that The Powers That Be already know about RPS and would be searching for it deliberately, not merely stumbling upon it.
If you really want to be paranoid, search only for your fandom, and see how long it takes you to come across some slash. For instance, typing Lars Skylar Ulrich into Google brings up metslash as the eleventh result and the DamonAffleckSlash Archive as the twentieth result. If you're going to be paranoid, be paranoid about that, which is a far more reasonable way for The Powers To Be to unknowingly stumble across RPS.
