I have been going over the list of recently deleted posts, to see what new there since my last visit, and I have noticed something strange.
One of the network-wide moderator has deleted a question. The moderator has left a comment pointing out that this thread was deleted due to a DMCA filing, i.e. legal reasons. This for itself raises questions, as the question is particularly uninteresting.
The reason I bring this up to meta is that I want to have a clear grasp on the question in the title: when do network wide moderators remove questions?
I mean, should they ever do that? I'd feel slightly safer if even a legal request were deleted by our local moderators, although I can understand if there is something which requires otherwise.
I posted this thread for two main reasons, the first is to alert the community that this has occurred and get some input on the topic; and the second is to find out whether or not there is some legal obligation that the network should delete the thread, or did they just prefer not to bother the local moderators.
