If any of the college's bullies actually read the case studies and blog entries on this website, I suspect they would rush to get together to deny that's the way any of it happened and to get their stories straight. Together they would build new memories from their faded recollections of events and they might even try to make their target seem like the bully instead of themselves (see counterattack).
Ironically, by getting together they would only identify themselves as bullies by demonstrating their us-versus-the-target attitude. If the group has to get to together to manufacture evidence to show they were not mobbing the target, they've already lost the argument that they are not bullies.
But, in any case it will be difficult for the bullies to explain away their past actions which are the very definition of bullying behavior. They won't want to believe that their behavior could be described as "bullying behavior." Bullies find it much easier to blame their target for their behavior than to perform even a little introspection. Never expect bullies to admit they acted like bullies even when presented with irrefutable evidence of their behavior.
As a tactic to take attention off their behavior, they might even claim this website is cyber-bullying. Of course I haven't used anyone's names on the website and there has not been any harassment, intimidation or retaliation involved. And, indeed, a few of my co-workers have guessed the wrong people were the bullies mentioned here. So I would think it would be hard to claim this website has bullied anyone.
But I still expect them to try. It's what bullies would do -- anything to avoid taking responsibility for their behavior.
