The locking of planets and gates has been suggested quite a few times and sadly the prospect of abuse, even by those in official factions is considered to be too great to risk.
I can see this thread spiralling towards a pointlessness so lets just remind ourselves why this is being done.
We are not trying to steal away stuff from indies, we're trying to promote a sense of community in the form of official factions. Like them or not those factions serve an important function, they represent the various happenings of the story and as a secondary function they generate better RP by teaching new players.
Therein lies the rub, independent players are for themselves, faction players follow their factions RP.
