Former commissioner and champion of the Stanford IM Beirut (that's beer pong for the uneducated) here. The university repeatedly threatened to shut us down, but since we weren't an official group that was tough. They did ban drinking games in dorm rooms, which thankfully wasn't enforceable, but things were headed in this direction back in the late aughts.

Back then, this stuff was theoretically in the name of safety, though that was totally misguided. When I got to my freshman dorm, the RAs told us to leave the door open if we were drinking, so they'd know if anything was wrong. In return, there would be no trouble. They held up their end of the bargain, and everyone was drunk but safe and free of administrative trouble. Even the Stanford sheriffs were well known for not giving you trouble unless you were flagrantly drinking in public or causing a real problem. Forcing people to hide their drinking didn't make anybody safer.

It's really a shame that the administration has chosen this direction. I genuinely don't know what the point is.
