Kudos to you Roberto et al. ,
I don't know if you will get anywhere legally with the disfellowshipping practice, but I think that the publicity will do its part in tarnishing the watchtower's image. Watchtower guards its "image" to the world scrupolously. If it feels that the world is watching....perhaps they may get to the point where they will stop the disfellowshipping practice. That would be a real victory
