I am no attorney, but I would suggest that depending on what the employee was arrested for, could give the employer cause? For instance, was it a DUI arrest, and is the employee an outside salesperson? Was it for endangering a child, and the employee works in a day care?
I find it interesting that the term used was 'pre-convicted"....was the employee in fact, actually convicted, and the employer found out by using this website?
You know, with the social media explosion, everyone is going to have to get used to the fact that we will have much less privacy.
Just my 2 cents...
