I've thought long and hard about posting this but I think it's fair that you all know.
'cod' is in fact a composite of many different people. As you are probably aware all internet sites are monitored by MI5 and The Special Branch. Mnet is no exception. When the site was created, and although it would appear to be of a 'fluffy' nature, MI5 were nevertheless interested. It would be too difficult and obvious to involve an undercover moderator in this kind of surveillance as the very nature of the work involves gaining the confidence of and personal information from posters. So, after several name changes, the character of 'cod' was established. 'cod' is in fact any given member of whichever team/shift is on duty in the MI5 buildings on the Southbank.
You will have noticed that 'she' has sons and is interested in fashion. This persona was chosen to enble 'her' to discuss what are considered to be feminine traits ie. fashion, and to discuss parenting boys only, as most of the MI5 operatives are male and could therefore identify. Her style of staccato and virtually unreadable posting ensures that the differences in expression/wording of any operative's posts will be unremarkable.
Although mnet members are usually a fairly benign bunch of people there have been issues which have made this level of surveillance worthwhile. Milupa brand and Tommee Tippee have been concerned at the increasing levels of hostility towards their products and are vigilant. Walls have ears.
