Quit hazing. Bring it up in the next meeting and adopt a strict no hazing pledge period with penalties for such activities. You may lose some brothers but you are better off without them.
Please note that there is always a degree of incrementalism with hazing that slips in and eventually someone will cross the line and a pledge gets hurt. You will be shut down and may open yourselves up to a huge lawsuit or in a worse case scenario jail time if you continue. Your National should reorganize your chapter at the very least.
I shake my "old" head in disbelief.
