What English township is the official technical namesake of broken profanity filters?

Image via WikipediaOf the various and sundry reasons we're all anxiously awaiting the semantic web, perhaps the most overlooked motivator is a desire for smarter profanity filters. This is especially true of two groups: Residents of certain English township which is the namesake of semantically dumb text filters, and a medieval aficionados who suffered rather comically at the hands of a rather famously stupid online profanity blocker.

Here's where you can learn about both:

• TechTalk Podcast #239: What is the synonym for the word “medieval” that exists only because of a malfunctioning profanity filter? 
• Geek Trivia: What English town is infamous for its role in testing early profanity filters? 

Both items answer both questions, but from opposite ends. I encourage you to consume both and decide which is better, and not just because I like farming page views to my friends and sidejob employers. (OK, mostly that, but not entirely.)
