Dont let your fear drive you insane. We have all been there... the fear, the guilt, the worry that god will reveal in some mysterious way that you were trolling an internet forum...
nobody cares. God dosent care. Neither do we. Just relax. Keep lurking... or not. Nobody knows who you are and nobody will track you down. If you dont post again nobody will even remember... or stay and see how deep the rabbit hole really goes...
