How to stop domain squatters: Years ago I remember cases where people who were deemed to just be "squatting" on a domain could have it taken away by a arbitration-like service at the registry. There were tests to help them decide if they were truly squatting or were using it themselves. Even so, opponents argued that there were many mistakes, that the arbitration services favored big companies and the process was abused to shut down legitimate comment (like "companyxsucks.com" sites) and the only people who really liked this system were the lawyers. Is this a route we want to go down? Have some kind of arbitration service who can decide if someone is a squatter and reclaim their domains?
