What benefit did you feel a site like that brought to the world? I'm not trying to be catty with that question, I'm honestly curious; a big part of websites nowadays is "We're trying to solve problem X in Situation Y by providing solution Z", and it's hard to see how that sentence gets filled out with JuicyCampus analogues unless it's "We're trying to solve the difficulty of being an asshole while remaining anonymous by providing a platform to do so". Was there some larger cause to CollegeABC, or was it simply "If we don't do it, somebody else will, so we might as well fill the void"?
It's interesting to note that the effective way to get people to stop using the site was to just make it unpleasant for them; that's a clever way to hit them where it hurts, I think.
In short: I originally ran the site at just a few schools, my alma mater being one of them. There, it was used productively and mean-spirited gossip was far from the norm. It helped people get honest advice, ask questions related to events around the school, etc.
When we "acquired" JC, everything changed, as the masses were coming in with an expectation of mean-spirited gossip. Despite my efforts, I could never meaningfully change that mindset.
I spent most of my 2 years running the site fending off competitors that would "let anything go" and were trying to "win" by maximizing the salaciousness of their content.
