This sort of persistent naughtiness can be quite difficult for planners to effectively deal with, though occasionally they get their own back in spectacular fashion; dodgy developers who demolished protected buildings are occasionally forced to rebuild them in full, which has to be quite satisfying. Perhaps they could make him put the twitter sign back.
I'm so glad I have always avoided social media sites like Twitter but it does give some good reading on HN.
