Here are two articles people might find interesting. The first is about how even a school like Grinnell, with no frats or big sports scene, has trouble dealing with this issue. How being small poses its own difficulties with punishments:

"On paper, Grinnell was doing everything right: It received praise for putting an affirmative consent standard in place in 2012, and its annual stats for sex offenses were among the highest per capita for colleges – suggesting students there were comfortable coming forward to report their assaults. The school even includes gender-neutral pronouns in its student handbook. There are no rowdy frats or big-time Division I sports stars to blame for rape culture, as has happened elsewhere.
But in some cases, Grinnell forced students to attend class with men the school acknowledged to have sexually assaulted them. The college made offenders write short apology letters to victims as their punishment. When some women struggled in classes due to stress related to their assaults, they say, the college pushed them off campus. And when students confronted Grinnell over its failings, student magazine editors lost their jobs and administrators told activists they were being intimidating."
The other is about the new policies at Penn and the potential for abuse of due process:

"Justin Dillon, former federal prosecutor and now a white collar defense lawyer, knows all too well the ways campus sexual abuse investigations can go wrong.
His litany of bizarrely skewed hearings is fraught with the potential for harm and tragic outcomes.
The college student brought up on charges of giving his girlfriend an unwanted kiss, more than a year after the relationship ended; an alleged rape victim who said friends had information the accused had raped others, but then declined to identify the friends; the hearing panel, composed of a librarian, a student dance major, and a professor of romance languages, whose job was to decide whether a sexual assault had occurred.
“It feels oftentimes that every new case I get is more absurd than the last. Sometimes you get people who are not old enough to drink, but are old enough to decide whether someone is a rapist,” says the Harvard-trained lawyer, based in Washington."
