Obviously they've picked the extreme examples for the news report, but it's no worse than what goes on during Raisin Weekend. Can you imagine the uproar if they tried to ban that? The rumours of it happening most years are bad enough!
Being made to drink a bucket of pedantry and procrastination while crabs paint your naked body with sarcasm paint would be a start. Also being beaten with the shaky stick.
I vaguely recall something a few years ago where someone at St Andrews was injured during an "initiation". I think the University made some kind of settlement and they managed to keep it (relatively) quiet. (HRH was still here at the time, so they didn't want any bad publicity.)
