This is from abroad, but you can print it and tweak it a bit to sound more American (get rid of the part referring to a fine in pounds) . It might help discourage an owner or authority figure from infringing on the space you occupy even if the legality it asserts does not apply. It might make them think twice before breaking in, and in that time hopefully you can get some mail addressed to yourself sent to the space to further slow down an eviction scenario. The classic loop hole is to get mail for everyone in your crew sent to the space because if/when an official eviction notice comes it will only be for the person they are aware is staying there - then when they come to evict someone else presents evidence they also live there and the process starts again. This game causes owners a great deal of stress and might lead to favorable negotiations. "Let us stay hear for free and we will maintain the property" starts to sound like a good arrangement when they realize possession is nine tenths of the law.
