Bryce, that is one of the unfortunate down-cast about Second-Life.
Land-Barons are given golden-ties by LL, and unfortunately some have become piggish with power about it. There is no fairness or accountability Land-Owners are governed by unless it violates their terms of service with Linden Labs or/and Real-Life laws. They can make rules, and they can break them, they can ban for the little things or no reason at all. That does not mean one has to be a rug just because someone owns land. They are not infinite power, and those who have behaved this way continously have earned sooner or later, some sort of retribution from those whom they've poorly handled by either loosing their customers due to their own poor management skills or a bad rep because their clients(whom they forget, bring them traffics/lindens in the first place) have become tired of being treated like horse manure.
You are not obligated to give them your traffic or lindens, just as they are not obligated to keep their virtual lands open to the public. Try to speak to the owner of the land if u can about your situation, but don't be surprise if your handed a sloppy or no response at all. Best is to find other places(which are plenty in the nude section) and not waste anymore of your time on places that have treated you unfairly. In the end, it's their lost and your under no condition to contribute to those places by giving them your traffic or lindens.
