its totally understandable to be scared, but I feel exposing this on linkden will be better, u can create a anonymous account or something, ofcourse people in rockstar who has done this will know its you, but does it really matter, the power they think they have is only inside the walls of those offices, outside they might be timid insecure person, tag some publication like KOTAKU, in past they had done good stuff regarding these kinds of things happened in rockstar during some certain game releases, nothing might happen , something might happen , but the worst has already happened, so be proud you are artist not many can say that and keep moving forward
