As we all know, anybody can register to be a Wikipedia "editor", and add relevant information to any listings.
I don't know if it still is so much anymore, but the QE2 Wikipedia page was once the jealously guarded playground of a single individual, so goes the scuttlebutt within the QE2 community.
Entries by other persons which were within Wikipedia's conditions were almost always quickly deleted by this person, as they seemed to believe that the QE2 page belonged to them alone.
From what I understand, "turf battles" are not uncommon on Wikipedia.
As Gore Vidal once famously said... "There's nothing true on Wikipedia"
but that's not really true either...
