Come on guys, history has shown that appeasment does not work I'm a very considerate neighbour, I don't do anything I hate having done to me and neither do my neighbours, we all exist in harmony. The problems arise when a bully is allowed to over step and the sheep just allow it so they nick some more. In the end even the pacifists must fight and the fight is much worse. I avoid agression by making it known that it is available to the bullies if required.
Anyway at the very least I'd take regular pictures and file a trespass suit.
