As others mentioned, some of the things you described are considered hazing. The tolerance for hazing in the US has gone down a lot in my lifetime. It likely still happens a lot, but when it is reported it is much more likely to be taken seriously.

For example, in my hometown there was a fraternity that threw a party and got an underage student so drunk that he died. Some of the fraternity members were charged with crimes related to the students death, and the fraternity was not allowed to operate on campus for two years. If that sort of thing had happened when my dad was in university, I doubt it would have even made the news.
