help. 

 An  ip address reverted my edit on PG (disambiguation)when it wasn't vandalism there subject was "rvv" and I checked it out (PG disambiguation is on my watchlist) and it turned out they reverted mine? All I did was add(i didn't blank the page or erased anything) was Peter Griffin. I undid there version but WHO IN THE HECK GAVE THEM AUTHORITY TO ERASE MY EDITS????? AND MOST IMPORTANTLY WHO SAID ADDING "PETER GRIFFIN" TO PG IS VANDALISM?
