No, I'm suggesting that if you are in a place where you can consider using this service then you are in a place you don't want to leave. There are other better ways of indulging yourself at work without giving your boss the opportunity he's been looking for.
Er, why does it have to be porn? I use the internet at work, well, for work related enquiries. Unfortunately, the software they have prevents me from looking at sites with certain words, etc. that trip the software.
Personally, I look at porn at home, but I use this regulalrly at work, and I'd have no problem with any boss asking me about it.
I'm not having a dig at you SC, if you included a piece of research in a presentation, a piece that would not ordinarily have been available and someone asks the wrong question you're screwed, you have to admit to using the service which would lead to the obvious conclusion that you are deliberately circumventing your companies IT policy. Welcome to your P45.
