Sub Judice applies to any publication of material that could bias a juror. Publication is inferred by making any information 'publicly available', so posting on this site is considered publication of information.
Comments that infer past tendencies, work habits, aggression and similar that draw a picture of the person would be considered contempt of court. The site even warns that it may be frequented by the press who could promulgate such information and make it viewable to a potential juror. There are strict guidelines that apply to reporting on a case once the suspect is charged until the verdict delivered and possibly further if appeal is probable.
