The Perlectionists or The Letter Lighteners

On the outer edges of not-quite London is an unremarkable semi-secret building where people are hard at work gathering Intelligence to protect the world from the dangers of Bad Information. Of all the departments, CB4 is the least important, and the things they study in the babbling wilderness of the internet could not possibly be considered intelligence by any stretch of the imagination. In a time of confusion, where everybody has an opinion and cannot wait to express it, CB4 is ready to track those beliefs, no matter how ridiculous.
The Ingenu, Twitchwell, the Luncher, and Madame Char (not their real names) are hard at work paying attention to inane conspiracy theories and addictively implausible ideas, so that you don't have to. It's a dirty job, but somebody (probably?) has to do it.
