One of the Volvo forums I follow recently went into service mode, and now shows the following message:
http://www.volvoforums.org.uk/forum.php
Which basically states that the forum has been intentionally closed because A) some business felt slighted and B) the forum owners felt they were at litigational risk. They also apparently got a lot of rude flack over the whole ordeal too, which I'm sure contributed to their deciding that it wasn't worth their personal risk to keep the forum open.
The website for this forum is in the UK, and the people concerned are likely there too, but the US seems to be ever so much more willing to feed its lawyer contingent. Is there any chance something similar could befall us?
