This stuff was generally known when I was in school. That was a long time ago, when no one cared much about frat hazing. Frankly I'd assumed it had been cleaned up by now. At best its embarrassingly infantile (yeah, I know, college kids) but at worst genuine harassment that grown-ups in charge should be stopping. Good thing that it finally is getting cleaned up.
I do wonder why now, though, as it was never really a secret and I can't imagine this is the first parent ever to complain. Some are suggesting the new president, or new regs. Perhaps, but strikes me its due to the stunning worldwide popularity the band achieved the past few years. The band is way more than our own OSU thing now. Its really become an important part of the University's public image.
