This is a problem which cannot be regulated out of existence. If I had to put my finger on what the issue here is, I'd say the TFM culture is to blame here. There are various influences online and in the media at large which influence our members as to what the "frat" lifestyle is usually far before they rush. When I was an active 15ish years ago, the main media influence on our members as to what the frat lifestyle was was a then 20-30 year old movie, Animal House which was clearly satirical.
This is the kind of thing we're dealing with now.

So we've moved from that satirical portrayal of the fun loving guys next door who binge drink and prank the administration to having these portrayals of these alpha male/aggro/blind drunk/hyper sexualized characters that every 19-20 year old kid wants to be exactly like.
And it's great because if your fraternity portrays itself as sufficiently fratty, you're going to sign these kids in droves and then figure out a way to manage their expectations after the fact. These kids want to be hazed, they want to binge drink and they expect to have those opportunities. The chapters which manage those expectations in a safe way are going to be fine, but those which glorify this sort of behavior are going to have problems.
Eliminating students from fraternities or fraternities from campus is only going to redirect this behavior to less regulated venues, so that's not a good answer. Schools might want to try to do a better job selecting which nationals they want on campus as some provide better resources and oversight than others.
