Like I said, I think CCP could be more aggressive in their combat against bots.
So no, I don’t think they are not banned cause they are good. I think they are not banned, cause CCP haven’t gotten around to it (cause of lacking resources invested in security team), or cause their policy does not allow for bans yet.
I could also be wrong and this is all a conspiracy, where CCP not only allows botters but prefers them in their game. Who knows, since we are not allowed to discuss these issues nor do we know how CCP security works.
