The old board was forced to shutdown by complaints lodged against it regarding content. The old Terms of Service were very restrictive with regards to content. Basically the hosting service had editorial control over the board content. This restriction was strategically exploited by complaining among other things, that "Negril" was being slandered, even though it is not a person.
Once the board was shut down, it couldn`t be reinstated until the offending material was removed, which of course was impossible, since access was removed - a real life catch-22. The new hosting service does not have editorial control and you all are solely responsible for what you write.
Regarding sharing material from other sites - it`s very common and even encouraged all around the internet today. As long as we are discussing ideas and not people`s personal traits, it`s probably all good.
In any event, a repeat forced shutdown of the board is highly unlikely.
