Spawn rape is specifically defined as the act of a person of having their crosshair or damage radius of a projectile aimed specifically at the place where a persons model or character spawn. This act of camping a particular spawn and then instantly killing the opponent or putting them at a large damage defecit from their initial spawn health as they respawn is spawn rape.
Spawn rape has been in multiplayer games from their very inception.
It is the map designers job to prevent spawn raping by designing levels that allow the player to move significantly from a protected spawn in order to be able to retaliate and be able to fire back on a camper, thus preventing spawn rape.
