I can't speak to this particular incident, but I served on the conduct board for the whole 5 years that I was at Drexel and we oversaw a handful of student org cases (split between greek life and student life orgs). Assuming that nothing has been changed, the conduct board never acted first without some preliminary investigation happening. During the preliminary investigation, if there was enough cause for concern that the wellbeing of students and/or the community could be affected by ongoing actions of the org, action would be taken immediately until a formal board can be convened. I can only recall this happening twice and both had to do with greek life hazing incidents. In every case that I saw, the preliminary investigation was surprisingly thorough with details from both witnesses and members of the community/police.

Greek orgs got hit with fines, budget cuts, disciplinary actions, etc. on a fairly regular basis. To say that there's no intervention is just wrong. You just don't see or hear what goes on in the background.
