Mathowie has a Medium post
detailing ongoing legal demands by Sundance Vacations to delete a 2010 Ask Metafilter
thread about their business, and later demanding personal information about users in that thread. Short version: Sundance, or somebody claiming to be from Sundance, may have doctored an unrelated court order to aim it at Metafilter.
The story has been picked up at BoingBoing, Popehat
(where Ken White has praise for how our fearless leader handled the situation) and presumably elsewhere as well.
