I'm sure you'd be happy to fund another wodge of cash for my (Government) employers connection to the 'net.
While misuse of facilties is a management issue, it's far easier to just limit access to innapropriate sites and save it ever having to be one.
We block most types of sites, all incoming attachments of any sort, all social networking sites, webmail sites and streaming media. Based on the growth patterns before we stuck the filtering software in, that's saved us (or, you, the taxpayer), a substantial sum of money in bandwidth costs and mail server hardware, as well as removing employee unproductivity opportunities. (Probably, the webcam rollout program isn't finished yet :-))
If that's wrong, well, I don't wanna be right...
