You're not allowed to remove roleplay that you've had with other players without their permission.
Full stop, no argument, no ifs, ands, or buts. You're not allowed to, you've never been allowed to, and you never will be allowed to. Doing so is not only an act of powergaming in and of itself, but a severely harmful move for not only your faction but the community at large. That's why the registration agreement puts all material made for and created by an official or unofficial faction as falling under a creative commons license; it's for the community, and for the faction, not for you.
Anyone who believes otherwise is severely mistaken.
(Wasn't Lyth sanctioned for this sort of thing, even?)
