You mention ‘classified’ in the facebook post and I agree with you that it has shortfalls. I believe, ‘confidential’, is better, and probably is good enough to refer to the concept. Look at the merriam webster definition #4[1] for ‘confidential’. I also think simply saying ‘dangerous information’ works. I can’t think of any other kind of dangerous information besides infohazards and the socially dangerous information you describe. Therefore if information is dangerous but it isn’t an infohazard it’s dangerous information [other].
