I was tickled by Baboonery taking some direct, and amusing, action against Foxtons. BD tends to try and wind up scammers on the internet, but that doesn't really have a local edge to it, unless there is a West Africa/SE23 angle on it. Nor does his attemts to wind up ticket touts on e-bay by selling free advice on how to avoid them.

Of course by not using McDonalds I may have driven them out of business but perhaps not.

Maybe someone can add some more interesting stories.
