Marking / flagging incorrect entries

Hi all,

I've recently found myself doing the same exercise as another poster on this thread to find potentially bogus entries - averaging postcodes per region and finding ones that are significantly outside where they belong.

This raises a question though, let's say I believe these codes are suspect and so does everyone else (indeed I've checked one or two on other websites which use more "official" postcode data), should these codes be removed or at least marked somehow as bogus?

If I'm going to use this data in a project of my own I could remove these entries having manually checked them, but then the data correction isn't being done in a shared way along with the data collection.

What's the best way of setting a feedback mechanism like this up?  If necessary I don't mind helping out?
