Islington council into some serious game theory. They offered the 1st person in our flats £50 to give them a copy of the shared front door key. Having failed, they now offered the 1st of us to comply £50 - but will otherwise change all our locks and recharge the costs to us all.
That's extortion, get evidence and let the police deal with them. I asked for an ASBO to be placed on a traffic warden at one point on Loftus Rd. Didn't work but it felt good...
