I had a stay in hospital a couple of years ago. The in-house (in-bed) Internet access blocked Serious Compacts along with almost every form of social media including Pistonheads and Mumsnet (don't ask...) the problem is a blacklist of filter words that is often used - lazily - to "protect" the user.
I suspect that using a term such as "gear porn" is enough to trigger the autonannies. I certainly know of an instance where using the name of a particular Northern English town was responsible for one of my employees having his emails to them blocked by an over-zealous public sector server. The irony was the town in question was where he was working for them on assignment...
... In fact, thinking about it, even my using the word "assignment" may be enough to get us blocked...
